TrainingPeaks is a long-established platform for endurance coaches and the athletes they work with, built around deep periodization tools and a coach-athlete workflow. FITIV gives you the same core training load metrics (TRIMP, TSS, acute and chronic load) in a mobile-first app that works with Apple Watch, Garmin, and Fitbit, for athletes who coach themselves.

What TrainingPeaks Does Best
TrainingPeaks has spent more than 25 years building tools for endurance coaches, and it shows in the platform's depth. The Performance Management Chart, which plots your fitness (CTL), fatigue (ATL), and form (TSB) over time, is a detailed version of that visualization. For athletes who want to understand long-range periodization, plan a peak for a specific race, and analyze how their training built fitness over a 12-month cycle, TrainingPeaks gives you more data to work with.
Nothing else matches its coach-athlete workflow. If you work with a coach who builds structured workouts with power targets, pace zones, and duration blocks, TrainingPeaks is the platform those workouts are delivered through. Coaches can review your completed workouts, compare planned vs. actual TSS, and adjust the training calendar in real time. FITIV doesn't replicate that.
TrainingPeaks also goes deep on structured workouts. You can define intervals with power or pace targets, specify warmup and cooldown protocols, and push those workouts to compatible Garmin, Wahoo, or other devices for execution. For athletes training by power or pace zones, this is a meaningful edge.
If you race with a Garmin head unit, TrainingPeaks' two-way sync with Garmin Connect is smooth and automatic.
What FITIV Does Best
For the self-coached athlete (which describes many recreational and amateur competitive athletes), TrainingPeaks is a platform built largely around a coach-athlete relationship you may not have. FITIV puts the same foundational training load metrics in one daily view next to sleep, recovery and readiness, using data from the Apple Watch, Garmin, or Fitbit you already wear.
The gap shows most on your phone. TrainingPeaks has iOS and Android apps that now show Fitness, Fatigue and Form, but it grew up as a web platform, and some of its deepest tools, like the strength workout builder, are still web-only. FITIV was built mobile-first, so your training load, readiness score, and workout logging fit the moments you actually use them: the morning check before you head out, the wrist glance between sets, the post-workout summary on the drive home.
TrainingPeaks' recovery data comes from other devices: it can sync HRV, sleep, and resting heart rate from wearables like WHOOP, Oura, and Garmin, or you can enter metrics by hand. FITIV puts HRV readiness, training load, and recovery scores in one app on one device.
TrainingPeaks has added strength training: coaches and Premium athletes can build strength workouts with sets, reps and weight on the web, and athletes log them in the mobile app. FITIV logs strength workouts with sets and reps right on your iPhone or Apple Watch, with hundreds of built-in exercises, a rest timer and progressive overload recommendations, and the heart rate from those sessions counts toward your training load like any other workout.
FITIV has a native Apple Watch app. TrainingPeaks doesn't. Its structured workouts can sync to Apple's Workout app, but it doesn't offer its own watch experience, readiness scores, or strength logging on your wrist.
Accounts and Access
| FITIV | TrainingPeaks | |
|---|---|---|
| Where you use it | iPhone and Apple Watch | Web, iOS and Android |
| Account types | Athlete accounts | Basic and Premium athlete accounts, plus coach accounts |
| Performance Management Chart | Not offered; Training Summary shows short- and long-term load | Premium |
| Coach required | No | No, but built around coach use |
TrainingPeaks Premium costs $19.95 a month or $134.99 a year on trainingpeaks.com. Basic accounts can log and sync workouts and work with a coach, but they don't include the Performance Management Chart or future planning. If your coach uses TrainingPeaks, you can connect it in FITIV from the More tab (•••) → TrainingPeaks and send your FITIV workouts there.
Honest Assessment: Where TrainingPeaks Wins
If you have a coach, or you're planning a detailed season around an A race (base, build, peak, taper), TrainingPeaks is the better fit: its shared calendar, planned vs. actual analysis, and long-range Performance Management Chart are built for exactly that. The same goes if you analyze every watt of indoor cycling data or build interval protocols to run on a Garmin head unit.
Who Should Choose FITIV
- Self-coached athletes who want TRIMP/TSS training load without a coach-centered platform
- Athletes who train on Apple Watch and want native, mobile-first training load tracking
- Hybrid athletes who mix strength training and endurance and want one tool for both
- Athletes who want HRV readiness integrated with training load, without a separate recovery wearable
- Athletes who want sleep, recovery, strain and training load together in one daily view
Who Should Choose TrainingPeaks
- Athletes who work with a coach using the TrainingPeaks coach-athlete workflow

Frequently Asked Questions
Does FITIV calculate TSS like TrainingPeaks?
Yes, in a similar way. FITIV calculates Training Stress Score from power when a workout has it, using your FTP, or from heart rate when it doesn't. TrainingPeaks adds pace-based rTSS for running and sTSS for swimming, plus more historical charting for athletes who want to analyze years of data.
What is the Performance Management Chart?
The PMC is a visualization of your fitness (Chronic Training Load), fatigue (Acute Training Load), and form (Training Stress Balance) over time. TrainingPeaks shows all three. FITIV's Training Summary shows your Short Term (ATL) and Long Term (CTL) load, the ratio between them, and a Training Status, but doesn't display a form (TSB) number. TrainingPeaks' charting is more detailed; FITIV's is built for a quick daily check on your phone.
Does FITIV work with Garmin like TrainingPeaks does?
Yes, in two ways: FITIV connects directly to Garmin Connect to bring in your Garmin workouts, sleep, and HRV, and many Garmin watches can broadcast heart rate to FITIV during a workout. FITIV reads from Garmin but doesn't send workouts to it. TrainingPeaks has a deeper Garmin integration and pushes structured workouts directly to Garmin head units, which FITIV does not do.
Can FITIV replace TrainingPeaks if I have a coach?
No. TrainingPeaks' coach-athlete workflow (shared calendar, planned vs. actual analysis, coach messaging) is purpose-built for that relationship. But you don't have to choose: connect TrainingPeaks in FITIV from the More tab (•••) → TrainingPeaks, and with Workout Sync set to Auto, FITIV uploads your GPS workouts when you finish them. Indoor and strength sessions can be sent from the workout's Share to menu (sets and reps stay in FITIV). Your coach keeps seeing your sessions while you use FITIV for daily readiness and strength tracking.
Does TrainingPeaks track HRV?
TrainingPeaks can display HRV and sleep data synced from wearables like WHOOP, Oura, and Garmin, or entered manually. FITIV reads HRV from the Apple Watch, Garmin, or Fitbit you already own and turns it into Recovery and Training Readiness scores, without a separate recovery wearable.
Can competitive athletes use FITIV?
Yes. FITIV calculates TSS from power or heart rate, tracks your short- and long-term load, and adds Training Readiness from your overnight HRV, which covers what most self-coached competitive athletes use day to day. Athletes who work with a coach on precise periodization, or who want pace-based run and swim TSS, will get more from TrainingPeaks.
