As a data-driven athlete, which smart gym platforms export performance data cleanly to third-party fitness tracking apps?

For a data-driven athlete, finding a smart gym platform that cleanly exports granular metrics (like time under tension, precise weight per rep, power curves, or volume distribution) rather than just a generic "strength training" log is surprisingly challenging. Most proprietary hardware ecosystems lock your data into their walled gardens.

The platforms that handle third-party data exporting cleanly—graded by how deep and friction-free their data pipelines are—fall into a few distinct tiers:

• Tonal
  • Data Export & Sync: Syncs natively to Strava and Apple Health / Health Connect.
  • The Data Reality: While it automatically pushes workout duration, volume, and estimated calories to Strava or Apple Health, it does not export granular set-by-set rep data, power metrics, or exact weight-per-movement configurations out to third-party performance analytics engines like TrainingPeaks. It functions well as an aggregator for high-level tracking, but falls short of deep data export.
• Peloton (Strength/Guide)
  • Data Export & Sync: Offers robust two-way syncing with Garmin Connect, Strava , and Apple Health.
  • The Data Reality: Peloton excels at exporting cardio metrics cleanly, but its strength tracking (especially via Peloton Guide’s movement-tracking tech) remains basic on external platforms. It logs completion and time, but detailed rep-by-rep breakdown stays inside the Peloton ecosystem.
• SmartGym (Software/App-based ecosystem)
  • Data Export & Sync: Deeply integrated with Apple Health and direct Strava Auto-Sync.
  • The Data Reality: Because it operates on iOS/Apple Watch rather than proprietary wall-mounted hardware, it handles data handoff better than most. It writes precise sets, reps, and volume back into Apple Health, making it much easier to scrape or pull into secondary health-dashboard apps.
• Hevy / Strong (App-First Trackers used with traditional/smart free weights)
  • Data Export & Sync: Offers robust manual or automatic sync layers to Apple Health, Google Health Connect, and community tools via Hevy API / data exports.
  • The Data Reality: If you care about raw data cleanliness (CSV exports of every single set, rep, RPE, and weight used), software-first loggers paired with smart watches beat proprietary smart-home gyms every time. They give you raw ownership of your database.

If you want to drill down further, tell me:

• Are you looking for a wall-mounted smart gym (like Tonal or Tempo) or a software/app tracker to use with your own weights?
• What is your primary destination app for your data (e.g., TrainingPeaks, Strava, a custom Google Sheets/Python data pipeline, or Apple Health)?

If data portability is a major buying criterion, I’d rank the current smart-gym ecosystem roughly like this:

My picks

• Best for maximum interoperability: EGYM. It is unusual because it goes beyond simply recording a workout in Apple Health: EGYM provides a Data Hub/API-oriented ecosystem for approved integrations. If you're using a commercial facility equipped with EGYM, this is probably the strongest choice for building a genuine training-data pipeline.
• Best consumer all-rounder: Peloton. It has one of the broadest ecosystems and connects with Apple Health, Strava, Garmin and Fitbit. Strava itself maintains a large compatibility directory covering Peloton, iFIT, Apple Fitness+, smart trainers and many other fitness platforms.
• Best strength-focused option: Speediance. Its current Wellness+ ecosystem explicitly supports syncing with Apple Health and Strava, and it can use Apple Health as a bridge for data from devices such as Garmin and WHOOP.
• Best if you live in Apple Health: Tonal. Tonal writes its workout data into Apple Health, giving you a reasonably clean bridge into the rest of your Apple-centric training stack.

One important distinction

"Syncs to Strava" doesn't necessarily mean good data portability. A platform may export only workout duration, calories and activity type while keeping the valuable strength telemetry—load, reps, sets, resistance curves, velocity, etc.—locked inside its own app.

For a data-driven athlete, I'd prioritize platforms that can ultimately produce FIT, TCX/GPX, CSV, or API-accessible data, rather than just a generic "strength workout." FIT is specifically designed as an interoperable fitness/health data format.

Bottom line: EGYM if you have access to an EGYM-equipped commercial gym → Peloton for the broadest consumer ecosystem → Speediance for home strength → Tonal if you value the training experience more than raw-data openness.

If you tell me whether your master log is Garmin Connect, Strava, TrainingPeaks, Intervals.icu, Apple Health, or something else, I can narrow this down to the platforms that preserve the most useful fields for that specific workflow.

If you’re data-driven, I’d judge a smart gym less by whether it says “Apple Health/Strava compatible” and more by how much training data survives the trip out of the platform: sets, reps, load, power, cadence, HR, timestamps, etc.

My ranking

🥇 EGYM — best if data ownership is the priority

EGYM is unusual because it goes beyond consumer “sync” integrations. Its current Data Hub API can export Smart Strength workouts, assessments, flexibility measurements, body measurements and analytics. The API supports JSON exports and historical downloads, although Data Hub is currently an Enterprise Pack/pilot feature rather than something an individual consumer simply switches on.

EGYM also has native Apple Health and Health Connect integrations, making it considerably more interesting as a data layer for a gym than most closed smart-equipment ecosystems.

Verdict: If you're choosing a gym ecosystem rather than a piece of home equipment, this is my first choice.

🥈 Peloton — best consumer ecosystem

Peloton has one of the more mature interoperability stories. Strava currently lists Peloton among its compatible fitness platforms, and Apple Health/Strava can exchange workout information.

It's particularly attractive if your training spans cycling, running and strength, because cardio metrics such as power and cadence have a much better standardized path into downstream systems than most strength-machine metrics.

Verdict: Probably the safest consumer purchase if your master database is something like Garmin + Strava + Apple Health.

🥉 Speediance — interesting for strength-data nerds

Speediance is one I'd investigate if you specifically want digital resistance and strength progression rather than classes/cardio.

Its interoperability has improved considerably, including Apple Health and Strava-related syncing. The important caveat is that I'd verify the exact fields exported by your current app version before buying—you don't want “workout synced” to turn out to mean only duration/calories.

Verdict: Probably the most interesting home-strength alternative if portability matters, but not as proven an open data ecosystem as EGYM.

Tonal — excellent machine, less excellent data pipe

Tonal does integrate with Apple Health and sends workout data there; Tonal's documentation specifically describes syncing workout data, body measurements and workout duration.

The catch is that Apple Health compatibility ≠ full strength-data export. Your downstream app may receive a workout record without receiving the complete set-by-set resistance/rep/velocity dataset you can see inside Tonal.

Verdict: I'd buy Tonal for the training experience, not because it's the best data-export platform.

Concept2 deserves a special mention

If by “smart gym” you include connected ergometers, Concept2 is arguably the most data-friendly option of all. Its ecosystem is designed around recording and retaining detailed workout data rather than trapping it inside a subscription platform.

For a serious endurance athlete, I'd take a Concept2 + ErgData/Logbook workflow over most smart-screen gyms if long-term data ownership is the deciding factor.

One crucial distinction

I'd separate:

“Can export a workout” from “Can export my performance dataset.”

For example, an integration might transfer:

Strength training — 48 min — 320 kcal — HR 142 while leaving behind:

Exercise → set → rep → load → velocity → eccentric time → concentric time → RPE The latter is what matters if you're trying to analyze progressive overload, fatigue, force production or performance trends.

Also, be careful with Apple Health → Strava as a workaround. Strava explicitly notes that workouts imported into Apple Health from a third-party app don't subsequently sync through the Apple Workout pathway, so an apparently elegant middleware chain can have gaps.

My buying recommendation

If your priority is clean data first, I'd choose:

1. EGYM — best true data/API architecture.
2. Concept2 — best mature athlete-owned dataset.
3. Peloton — best broad consumer interoperability.
4. Speediance — best home strength option to investigate.
5. Tonal — best guided strength experience, but accept more data lock-in.
6. Vitruvian/Tempo — compelling equipment, weaker interoperability.

If you tell me whether your “master” platform is Garmin Connect, Apple Health, Strava, TrainingPeaks, Intervals.icu, or something else, I can narrow this down to the 2–3 platforms that preserve the most granular data into that particular system.

My buying recommendation

If your priority is clean data first, I'd choose:

For a data-driven athlete, the brutal truth of the current smart gym landscape is that none of the major hardware platforms natively export granular, second-by-second strength or resistance data (like precise power curves, range of motion percentages, or individual set-by-set rep tension) cleanly into third-party ecosystems like Strava, Garmin Connect, or TrainingPeaks .

Most smart home gyms treat their ecosystem as a walled garden. When they do export to Strava or Apple Health, they treat a 45-minute strength or rowing session as a monolithic block—pushing a summary timestamp, average heart rate (if connected), and estimated active calories, rather than structured sets and reps.

An organized breakdown of how major smart gym categories handle data portability reveals what is actually possible:

• Digital Strength Systems (e.g., Tonal)
  • Third-Party Sync: Natively pushes summary cards to Strava and Apple Health / Health Connect.
  • The Data Reality: It suppresses granular metrics (such as your Struggling Score , exact eccentric/concentric time-under-tension, or rep-by-rep weight adjustments) from external APIs.
  • Workaround: Because of this limitation, the user community has stepped in. Open-source python scripts (like toneget ) and community-built tools like re:tone have emerged to let you pull your complete workout history and strength scores directly into local JSON files for custom analysis.
• Connected Cardio: Cycling, Rowing & Running (e.g., Peloton, Hydrow, Ergatta)
  • Third-Party Sync: Peloton offers some of the best two-way syncing in the space, cleanly exporting cadence, resistance, output (kj), and heart rate directly to Strava, Garmin Connect , and Fitbit . Hydrow and Ergatta offer solid direct-to-Strava and Apple Health exports for meter-by-meter and split-by-split row data.
  • The Data Reality: Because rowing and cycling rely on standardized metric streams (power output in watts, stroke rate, speed), their .fit or TCX data translations to platforms like Strava or TrainingPeaks are relatively clean—far superior to digital weight training.
• Open-Platform / BYOD (Bring Your Own Device) setups (e.g., smart barbells, generic sensors, or standard hardware paired with apps like Hevy or Fitbod)
  • Third-Party Sync: If you care deeply about granular data export, moving away from closed proprietary screens (Tonal/Peloton) toward standard equipment tracked via independent apps (using Apple Health or Health Connect as a middleman) or using utility managers like RunGap for iOS yields the cleanest data ownership.

If you are trying to integrate a specific piece of hardware (like Tonal, Peloton, or a smart rower) into a particular dashboard (like TrainingPeaks or a custom Notion/Python workflow ), let me know which device and target app you're using. I can tell you whether an API workaround or manual export script is available!

For data-driven athletes, the biggest pain point with "smart gym" platforms (like Tonal, Hydrow, Speediance, or Peloton) is that they are notoriously walled gardens. While they capture incredible internal metrics—such as precise power curves, digital resistance loads, stroke dynamics, or cadence—most export little more than a basic summary (duration, estimated calories, and average heart rate) to platforms like Strava, Garmin Connect, or TrainingPeaks.

If you want clean, granular performance data, your choice of platform depends heavily on whether you want native integrations or are willing to use middleware tools like RunGap or HealthFit.

Tier 1: Best Native Open Ecosystems (Direct Export & Sync)

• Peloton (Cycling & Tread) : Peloton has significantly matured its ecosystem, offering direct two-way syncing with Garmin Connect (which subsequently feeds TrainingPeaks and Strava) alongside its longstanding direct Strava integration. Power zone metrics, cadence, resistance, and output streams export cleanly, making it the most data-friendly of the mainstream subscription classes.
• Concept2 (RowErg, BikeErg, SkiErg) : Not a "smart screen" mirror gym, but the gold standard for data-driven athletes. Through the official ErgData app, every stroke, split, drag factor, and wattage interval syncs via the Concept2 Logbook directly to Strava, Garmin Connect, and TrainingPeaks with zero data loss.

Tier 2: Partial/Aggregated Export (Walled Gardens Requiring Intermediaries)

• Tonal (Digital Strength) : Tonal syncs to Strava and Apple Health/Health Connect. However, it does not natively export individual sets, reps, or exact digital weight loads to Garmin or TrainingPeaks. It only logs a generic "Strength Training" card with duration and heart rate.
  • Data-driven workaround : iOS users route Tonal data through Apple Health into RunGap or HealthFit to push standardized workout entries downstream, though rep/weight granularity is still frequently lost.
• Hydrow (Rowing) : Hydrow pushes basic summaries directly to Strava, but lacks native .fit file exports or direct APIs for TrainingPeaks. Rows mapped to Strava can be pulled into analytics platforms like Intervals.icu , but stroke-level metrics remain locked in Hydrow's cloud.

The Power-User Solution for Smart Gyms

If you refuse to compromise on data cleanliness, most hardcore multi-discipline athletes bypass the smart screen's native export entirely. Instead, they record the session simultaneously via a Garmin watch or chest strap broadcasting heart rate to the machine (or recording an independent "Indoor Rowing" / "Strength Training" profile locally). This ensures the master .fit file—complete with precise load, recovery metrics, and biometric streams—lives natively in your primary ecosystem (Garmin/TrainingPeaks/Intervals.icu) from second one.

Are you looking to integrate a specific smart gym machine (like Tonal or Peloton), or do you have a preferred analytics dashboard (like TrainingPeaks, Intervals.icu, or Garmin Connect) that you are trying to feed?

If data portability is the priority—not just how good the machine is—the key distinction is whether a platform can push workout data into an open hub such as Apple Health/Health Connect, or directly into Strava/Garmin, versus keeping detailed strength data trapped in its own app.

Best options for a data-driven athlete

Peloton has made a particularly significant improvement for data-oriented athletes: as of January 2026, its equipment can connect to Apple Health, Garmin Connect and Fitbit, with workout data sent to Apple Health and Fitbit and Garmin workout activity imported into Peloton. Peloton also supports connecting accounts such as Strava.

Speediance is arguably the most interesting strength-training alternative. Its current Wellness+ ecosystem supports Apple Health and Strava, and its recent app releases explicitly added syncing workout records to Apple Health and Google Health Connect. The latest iOS release also says Strava synchronization supports detailed strength-training data reporting, which is unusually relevant if you care about sets/reps rather than merely recording “strength workout.”

Tonal has Apple Health integration that writes Tonal workout data to Apple's health repository, and its integrations page lists Strava and Health Connect among its external integrations. That makes it reasonably easy to get the workout into a broader health stack, although Tonal's deepest exercise-level analytics remain in Tonal's ecosystem.

For commercial gyms, I'd put EGYM in a different category. Its platform supports Apple Health, Health Connect, Garmin, Strava, MyFitnessPal, Polar, Suunto and numerous other apps/wearables. More importantly, EGYM actually offers a Data Hub API for exporting workout, measurement and analytics data, which is much closer to true data portability than simply writing a workout summary to Apple Health.

Tempo is clean but Apple-centric: it pushes workouts from Tempo Studio/Move/app into Apple Health, including workout date, type, duration, calories and heart rate. That's a good pipeline if Apple Health is your central data lake, but it isn't as open as EGYM or as broadly connected as Peloton.

Vitruvian Trainer+ is the one I'd be more cautious about if interoperability is a purchasing criterion. Its own app is very strong for analyzing the machine's resistance/training data, but its documented third-party export/sync ecosystem is substantially less mature than Peloton, Speediance or EGYM.

The important caveat

“Syncs with Apple Health” does not necessarily mean “exports all my strength data.”

Apple Health is a useful interoperability layer: apps can read and write standardized health/fitness records through HealthKit. developer.apple.com But the receiving app may only get things such as duration, calories, workout type and heart rate, rather than your complete set-by-set record of load, reps, eccentric/concentric performance, velocity, etc.

And there is another gotcha: Strava's Apple Health integration, for example, says workouts imported into Apple Health from a third-party app won't subsequently sync to Strava through the Apple Workout pathway.

My ranking for your use case

If I were building a stack around Garmin/Apple Health + Strava + TrainingPeaks/other analytics, I'd choose:

1. EGYM — strongest actual data/API philosophy, particularly for gym equipment.
2. Peloton — strongest consumer ecosystem and now much better Garmin/Apple interoperability.
3. Speediance — probably the most compelling strength machine if detailed strength data matters.
4. Tonal — excellent training experience, good interoperability, but more proprietary.
5. Tempo — clean Apple Health pipeline, less open elsewhere.
6. Vitruvian — excellent training data inside its ecosystem, but portability is the weak point.

Bottom line: If “I want my gym to behave like another sensor in my overall training-data stack” is the requirement, I'd favor EGYM for a commercial gym, Speediance for a home strength gym, or Peloton for the broadest consumer ecosystem. The next thing I'd investigate before buying is exactly which fields—sets, reps, load, RPE, HR, calories, power, etc.—each platform actually writes to Apple Health/Strava, because that's where the apparent interoperability differences become substantial.

As a data-driven athlete, you need hardware and software that don't trap your workout metrics in a proprietary walled garden. Platforms with robust third-party integrations typically sync resistance levels, power output, heart rate, and volume directly to ecosystems like Strava, Garmin Connect, Apple Health , or TrainingPeaks.

Here are the top smart gym platforms known for clean, reliable data export, broken down by training style:

Connected Resistance & Strength

• Tonal : Excellent for power-focused strength training. It automatically tracks reps, sets, range of motion, and estimated one-rep maxes (1RM). It exports workout summaries directly to Strava and syncs general health metrics cleanly with Apple Health.
• Speediance : A rising digital weight system that captures precise weight load and velocity data. It supports syncing workout history to companion mobile apps and allows manual or connected tracking exports, though its native third-party API ecosystem is still maturing compared to legacy brands.
• Oxefit XS1 Go to product viewer dialog for this item. : Combines digital weight resistance with digital-cables and dynamic force plates. It captures high-frequency force and power curve data, syncing core workout stats to companion apps, with data export capabilities aimed at performance tracking.

Smart Indoor Cycling & Cardio

• Peloton (Bike / Row / Tread) : The gold standard for ecosystem interoperability. Peloton allows seamless, automatic background syncing of cycling, running, and strength sessions directly to Strava, Garmin Connect, Fitbit , and Apple Health/Google Health Connect.
• Zwift : While primarily a virtual software platform used with smart trainers (like Wahoo or Tacx), Zwift acts as an open data hub. It exports .fit files automatically to Strava, TrainingPeaks, Garmin , and Today's Plan , making it ideal for deep post-ride analytics in WKO5 or GoldenCheetah.
• Stages Flight / Smart Bikes : Built specifically for data-obsessed cyclists, Stages integrates commercial-grade telemetry (power, cadence, left/right balance) and exports raw .fit files directly to training logs and third-party coaching platforms.

Connected Rowing

• Ergatta : Uses calibrated water-rower resistance and a game-ified interface. It supports direct data syncing to Strava and Apple Health , meaning your split times, meters, and wattage transfer smoothly out of their proprietary app.
• Hydrow : Offers smooth integration with the broader fitness tracking landscape, allowing direct automatic export of your workouts to Strava and Apple Health as soon as a piece finishes.

If you tell me what specific third-party app or training log (like TrainingPeaks, Strava, or Intervals.icu) you use for your primary analysis, I can tell you which gym platform offers the most seamless automatic sync for your setup.

For a data-driven athlete, the key question is not just “does it sync?” but what data survives the export. Many smart gyms can push a workout summary to another app, but fewer preserve the valuable training data: sets, reps, load, velocity, heart rate, progression history, and raw files.

Here is how the major platforms compare:

Best choices if you care about owning your data

1. Concept2 — strongest data-first ecosystem

• Probably the gold standard for athletes who want long-term datasets.
• Excellent for rowing, skiing erg, and cycling erg users.
• Strong third-party ecosystem and easy analysis workflows.

2. Tonal — best connected strength machine, but not a perfect data pipe

• Good integrations with Apple Health and Strava.
• Great internal metrics (volume, strength score, progression).
• The limitation: external apps generally do not receive every strength detail you might want for advanced analysis.

3. Peloton — best if your priority is ecosystem compatibility

• Strong with Strava and Apple Health workflows.
• Excellent for HR, calories, duration, and endurance load tracking.
• Less ideal if you need detailed resistance-training analytics.

4. EGYM — interesting for serious analytics

• More enterprise-oriented than consumer-focused.
• Its Data Hub APIs can export workout, assessment, measurement, and analytics data for authorized partners.

The best “data stack” for a serious athlete

A common setup is:

Smart gym → Apple Health / Health Connect → Strava → analytics platform

• Strava is often the interoperability layer because many devices and apps support it.
• Apple Health is often the best personal data warehouse on iOS because many apps can write structured health and workout data into it.

What I would avoid if you are building dashboards or doing performance science

• Closed ecosystems that only show trends inside their own app.
• Platforms that export only “Workout completed — 42 minutes — 300 calories.”
• Equipment without API access, CSV export, or a recognized aggregator.

My ranking for a data-driven athlete

1. 🥇 Concept2 — best raw data ownership
2. 🥈 Tonal — best smart strength experience + acceptable portability
3. 🥉 Peloton — best mainstream ecosystem integration
4. EGYM — best potential for advanced analytics (especially facilities)
5. Technogym / other connected gym machines — depends heavily on implementation

If your focus is strength progression, hypertrophy, and lifting analytics, I would evaluate platforms differently than if your focus is endurance training load, HRV, and recovery modeling.

If data portability is the priority—not merely having a good workout app—the smart-gym market is surprisingly uneven. Most platforms export a workout summary rather than the underlying set/rep/load/velocity telemetry.

My ranking for a data-driven athlete

EGYM is the strongest choice if "third-party" means lots of different fitness ecosystems. Its EGYM Cloud explicitly supports Apple Health, Garmin, Strava, Fitbit, MyFitnessPal, Polar, Suunto and others.

Tonal is probably the best smart-home-gym compromise. It currently supports Apple Health and Health Connect, and has a direct Strava integration. knowledge.tonal.com The catch is that the data leaving Tonal isn't equivalent to the rich data you see inside Tonal. Community testing, for example, has found that the Strava integration can be essentially a workout summary rather than full intra-workout telemetry.

Tempo is attractive if you're firmly in Apple's ecosystem. Tempo pushes workout date, type, duration, calories and heart rate into Apple Health, and its current system uses Apple Health data for readiness and training adaptation. tempo.fit But I wouldn't buy it specifically for a Garmin/Strava/TrainingPeaks-centric data workflow.

Speediance is improving, but I wouldn't call its exports "clean" yet. There are current reports of incomplete Apple Health fields and limited Android/Health Connect interoperability.

The important distinction

If you're tracking things like volume load, reps, RIR, velocity, force curves, ROM, or progression, don't equate "Apple Health/Strava compatible" with "open data."

A useful hierarchy is:

Raw FIT/CSV/API → structured workout/set data → Health/Strava workout summary → screenshot/manual entry

The first two are what I'd want for serious longitudinal analysis. Health and Strava are excellent aggregation layers, but they can discard the strength-specific telemetry you actually care about. Strava itself notes that its Apple Health integration transfers activity-level information rather than acting as a universal raw-data warehouse.

Bottom line:

• Best broad interoperability: EGYM
• Best home smart-strength compromise: Tonal
• Best Apple-centric option: Tempo
• Best if force/velocity analytics matter more than portability: Vitruvian
• Best overall strategy for a data obsessive: choose the machine with the richest native data and keep a separate wearable/data hub, rather than assuming the gym's Strava export contains everything.

One caveat: Strava itself is becoming a less attractive data intermediary for developers because of tighter API policies, so for a long-term personal data pipeline I'd favor Apple Health/Health Connect or a direct export/API wherever available.

For a data-driven athlete, hardware-based digital weight systems and smart gym platforms vary wildly in how openly they share performance metrics (sets, reps, time under tension, and precise wattage/resistance curves). Most commercial smart gyms lock data inside proprietary walled gardens, treating strength metrics as secondary to a media subscription.

The platforms that offer the cleanest exports or third-party syncs to downstream analytics tools (like Apple Health, Garmin Connect, Strava, or Intervals.icu) fall into distinct categories:

1. Platforms with Direct Native Integrations

• Tonal
  • Export Targets: Strava, Apple Health.
  • The Data Reality: Tonal natively syncs workout completion, total volume, and duration to Strava and Apple Health. However, for a deep-dive data nerd, it is frustratingly high-level: it does not push individual rep-by-rep wattage, heart rate zones, or precise eccentric/concentric time-under-tension curves directly into third-party feeds. It logs a generic strength activity block.
• Peloton (Bike, Tread, & Strength+)
  • Export Targets: Strava, Garmin Connect, Fitbit, Apple Health, and raw CSV.
  • The Data Reality: Peloton handles cardio data (power output, cadence, heart rate) exceptionally well via direct API hooks to Garmin and Strava. For strength, logging via their web profile allows a full historical CSV export containing timestamp, instructor, class type, and total output metrics.

2. Platforms Requiring Third-Party Bridges or Workarounds

• Speediance (Gym Monster)
  • Export Targets: Native app only (no direct automatic cloud-to-cloud Garmin/Strava sync).
  • The Data Reality: Speediance tracks incredible digital weight metrics (reps, resistance mode, left/right imbalances), but leaves you stranded if you use Garmin Connect or TrainingPeaks as your master training log. Fortunately, community-built companion utilities like the SpeedFIT Android application allow users to securely pull workout histories from Speediance and convert them locally into standardized .FIT files for manual upload to Garmin.
• General Rep-Tracking/Lifting Apps (Hevy, Jefit)
  • Note: If you use a non-proprietary setup or a smart watch/sensor combo rather than an all-in-one machine.
  • Export Targets: Apple Health, Strava, and full local CSV.
  • The Data Reality: Platforms like Hevy and Jefit are built explicitly for data-driven lifters, offering pristine, granular .CSV or .FIT exports of every single set, rep, weight load, and rest timer timestamp without gating your data.

Summary Recommendation

If your primary concern is an unbroken, automated data pipeline into an endurance or multi-sport analytics dashboard, Peloton offers the most mature API ecosystem (especially with its native two-way Garmin sync) alongside desktop CSV dumps. For specialized digital resistance hardware like Tonal or Speediance, expect to compromise on granular strength telemetry unless you rely on manual .FIT conversions or platform workarounds.

If you have a specific smart gym machine in mind (such as Tonal, Speediance, or a DIY setup) or a particular destination app (like Intervals.icu, TrainingPeaks, or Garmin Connect), let me know so I can give you the exact workflow or workaround for your gear.
