Trayner AI

Trayner is a gym app that checks your lifting form from a phone video and tracks your workouts over time. Key features: • Film one set to score every rep • Tracks 33 body points to measure depth, angles and tempo • Plain-language cues to fix your next set • Live Coach counts reps and cues you mid-set through your earphones • Suggests your next weight and adjusts after a short night's sleep • Import your history from Hevy or Strong To start, prop your phone about two metres away at hip height, pick a measured lift such as bodyweight squat, bench press, Romanian deadlift, or overhead press, and hit record. Trayner scores each rep against a rubric for that lift and highlights one clear fix instead of a wall of numbers. You can pin a cue so it appears the next time you train that movement, and every check is saved per lift, so you can see your technique trend alongside your weights. Trayner also plans training around recovery. Suggested weights adapt when your sleep has been poor, and nutrition and recovery tracking help shape tomorrow's session. Logging workouts is free, and your first 14 days include Pro features such as Form Check and Live Coach. Built for lifters who want technique feedback without hiring a coach, from beginners learning squat depth to experienced athletes refining bench press tempo. It suits home gym users and anyone moving over from another workout logging app.
