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. —— FREE — Unlimited workout logging — AI program generation — Progress tracking and personal records — Apple Watch support — Nutrition logging PRO — £9.99/month or £29.99/year — Daily AI session adaptation — Weekly intelligence report — Volume landmark analysis — Correlation intelligence — Plateau detection and deload recommendations —— Subscriptions are optional.
