Trainiva is the AI coach that changes your workout to match how recovered you really are. YOUR WORKOUT, ADAPTED EVERY DAY Trainiva reads your sleep, resting heart rate and HRV from Apple Health and compares them with your own 30-day baseline. Fully recovered? You get an extra set and a push for a record. Short night? A lighter, shorter session. One tap switches back to your original plan. LIVE FORM CHECK WITH YOUR CAMERA Point your iPhone at yourself and Trainiva counts reps and flags form on squats, push-ups, lunges, overhead press, curls and tricep dips. Body tracking runs on-device: no video ever leaves your phone. A PLAN THAT LEARNS Tell Trainiva your goal, your equipment and your time. Every set you log teaches it something: weight and reps go up when you're ready. PROGRAMS FOR EVERY DAY โ€ข Home, gym and outdoor sessions of 15, 30 or 45 minutes โ€ข Hybrid race stations: lunges, burpees and squats, ready to pair with a GPS run โ€ข Keep your muscle: controlled one-movement-per-minute strength for anyone losing weight โ€ข AMRAP, EMOM and For Time WODs โ€ข Cardio with GPS route, pace and distance โ€ข Low-impact sessions with voice guidance โ€ข Mind Reset: slow, voice-guided movement and breathing to bring stress down TRAIN HANDS-FREE Log a set by saying it: "12 reps, 20 kilos". Follow sets and rest from the Dynamic Island and Lock Screen. Ask Siri "What's my recovery in Trainiva?" LOG LIKE A PRO โ€ข Your last weight and reps next to every exercise, with a suggested jump when you're ready โ€ข Supersets: pair two exercises with no rest in between โ€ข Warm-up sets calculated from your working weight โ€ข Plate calculator in kg or lb โ€ข A note on each exercise: seat height, grip, anything to remember โ€ข Weekly sets per muscle and your training load at a glance โ€ข The screen stays on while you train REAL PROGRESS Streaks that survive a rest day, automatic personal records, weekly volume, body progress and a monthly report you can share.
