STRIVN — AI Strength Coach
Most fitness apps record what you did. STRIVN tells you what to do next.
Powered by GPT-4o and built on exercise science principles, STRIVN is the only strength training app that adapts your program week to week — based on your actual performance, recovery data, and training history. No generic plans. No passive logging. A coach that learns.
——
AI-GENERATED PROGRAMS
Tell STRIVN your goal, experience level, and how many days you can train. It builds a complete, periodised program — compound movements first, volume calibrated to your level, rep ranges matched to your goal. Push/Pull/Legs, Upper/Lower, Full Body, or custom.
ADAPTIVE DAILY COACHING
Every morning, your AI coach reviews your Apple Watch recovery data — HRV, sleep, resting heart rate — and adjusts today's session accordingly. Peak recovery day? Push harder. Low HRV? Volume is pulled back automatically. The program responds to your body, not a calendar.
AUTO-PROGRESSION
Hit the top of your rep range on every set? STRIVN increments your weights automatically for next session. Progressive overload without the spreadsheet.
WEEKLY INTELLIGENCE REPORT
Every week, GPT-4o analyses your training, nutrition, and recovery data together — identifying strength trends, volume landmark status, plateau warnings, and correlations between your diet and performance. The kind of insight a £100/hour coach would give you.
VOLUME LANDMARK TRACKING
Built on MEV/MAV/MRV theory. See exactly where each muscle group sits — below minimum effective volume, in the optimal adaptive range, or approaching your maximum recoverable volume. Train smarter, not just harder.
NUTRITION LOGGING
Log meals manually, scan barcodes, or photograph your food — GPT-4o Vision identifies it instantly. Track calories, protein, carbs, and fat. Your nutrition data feeds directly into the AI coaching layer.
APPLE WATCH
Log sets from your wrist. Real-time heart rate, rest timer, and workout controls — all without touching your phone.
RECOVERY INTELLIGENCE
HRV, sleep quality, resting heart rate, and steps synced automatically from Apple Health. Your recovery score is recalculated daily and informs every AI recommendation.

Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
Fixes for a few things that could trip you up while setting up your programme:
- Your programme can no longer be edited while a workout is in progress — you'll be prompted to finish or discard the session first, so your live workout and your programme can't fall out of sync.
- The Save button on the programme builder is no longer hidden behind the active workout bar.
- Unsaved programme changes are now kept if you leave or close the app, and offered back the next time you open the builder.
- Clearer wording for the Custom split option during setup, so it's obvious you'll be picking your own exercises and training days.
- Removed an incorrect week number showing on custom programmes.
