Stop guessing.
Train with intent.
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.
Join 500+ lifters already on the waitlist. No spam, ever.
Your fitness app is a glorified notebook
Most apps record what you did. None tell you what to do next. You're left guessing on volume, intensity, and recovery — hoping something works. STRIVN changes that.

every single week.
GPT-4o analyzes your training logs, recovery data, and progress trends to rebuild your program weekly. Not a template — a living, breathing plan that adapts to you.

- Weekly auto-adjustments based on performance

Catch stalls before
they cost you months.

- Automatic program adjustments to break through
- 1RM prediction and strength forecasting
Train when ready.

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.
Intermediate lifter, 2 years training
Built for every stage

"Your first 12 weeks, planned by AI."

You track everything but still guess on programming decisions. STRIVN gives you periodization planning, 1RM prediction, and fatigue modeling.
