The first AI fitness tracker that doesn't just log your workouts — it tells you what to do next based on your actual recovery and performance.

The Problem
Your tracker is a diary,
not a coach.
You track every set, every rep, every meal. But you're still plateauing. That's because apps like Hevy and Strong are passive logbooks — they record the past but never advise on the future. You deserve more than a digital notebook.

Core Features
Intelligence, not just logging.
STRIVN combines AI coaching, biometric data, and adaptive programming to build the training plan your body actually needs.
Your program rewrites itself
every single week.
After every session, GPT-4o analyzes your performance — volume, intensity, RPE, and recovery signals. It then adapts next week's program to keep you progressing. No more static plans you follow for months hoping something changes.
- Personalized 12-week programs generated on signup
- Weekly auto-adjustments based on logged performance
- Deload weeks triggered automatically when fatigue accumulates
- Post-workout AI insights after every session
Your plateau isn't a fitness problem.
It's a data problem.
STRIVN monitors your strength progression across every lift. When it detects 3+ weeks of stagnation, it alerts you and automatically restructures your programming — adjusting volume, intensity, and exercise selection to break through.
- Real-time plateau detection across all major lifts
- AI-generated fix: volume adjustments, exercise swaps, deload protocols
- 1RM prediction based on your training history
- Strength progression charts with trend analysis
Train when your body is ready.
Rest when it's not.
STRIVN syncs with Apple Health, Oura Ring, and WHOOP to pull your HRV, sleep quality, and resting heart rate. It calculates a daily recovery score and adjusts today's workout intensity accordingly — so you never overtrain or undertrain.
- Daily recovery score from HRV, sleep, and resting HR
- Apple Health, Oura Ring, and WHOOP integration
- Auto-adjusts today's session based on readiness
- Weekly recovery trend analysis and fatigue alerts

Beta Feedback
What early testers are saying.
"STRIVN caught a plateau in my bench I didn't even notice. Changed my volume and I hit a 20lb PR two weeks later."
Marcus T.
Intermediate lifter, 3 years training
"I've used Hevy for a year. STRIVN is what I always wished it could be — it actually tells me what to do instead of just recording what I did."
Sarah K.
Switched from Hevy
"The recovery score changed how I train. I used to push through fatigue. Now I know when to back off and when to go hard."
Jake R.
Oura Ring user, 2 years training
