How Xert Works
Xert is built on a simple insight: your body tells you exactly what it can do. We just help you listen.
Discover Your Fitness Signature
Connect your Strava or Garmin account and Xert analyzes every watt you’ve ever produced. Within minutes, it calculates your Fitness Signature — three numbers that define your cycling capability:
- Peak Power (PP) — Your maximum instantaneous power output
- High Intensity Energy (HIE) — Your capacity to sustain hard efforts above threshold
- Threshold Power (TP) — Your sustainable power, just like your FTP
These three numbers paint a complete picture of your physiology and update automatically with every ride.
Your signature updates with every ride
Unlike a one-time FTP test, Xert continuously recalculates your fitness from every activity. No separate test. No disruption to your training.
Training Programs that adapt to how you actually feel
Did yesterday’s ride wipe you out? Xert knows. Did you skip a rest day? Xert lets you adapt the plan. Your plan is always current — never stale.
Improve with Adaptive Training
Whether you just want daily recommendations to keep improving or a highly-structured scheduled training plan to reach a specific outcome, Xert’s Adaptive Training Programs are there for you. Like your own personal coach that recommends the right workouts you need to do, it considers:
- Your current Training Load and recovery status
- Your current fitness level – Threshold Power, High Intensity Energy and Peak Power
- Available time to train
- Your training outcome – improvement goal, event or race
- Your current progress
Xert takes the guesswork out of every training day and helps you hit your training goals.
Perform & Break Through
Train on a variety of platforms — Garmin, Wahoo, Zwift, Rouvy, Xert EBC for Android/iOS and more. Every completed ride is automatically uploaded and analyzed by Xert.
When Xert detects that you’ve exceeded your previous limits, it marks it as a Breakthrough — real-time confirmation that your fitness has genuinely improved.
Your Fitness Signature updates immediately, and Xert recalibrates your next workouts accordingly.
Breakthroughs are real
Not a badge. Not a streak. A breakthrough means your actual fitness ceiling has risen — proven by power data, not guessed at.
