Trayner AI

Trayner is your AI coach for training, nutrition, and recovery — a complete fitness companion that plans your workouts, logs your sets, checks your form, tracks your food, and tells you when you're ready to push. AI FORM CHECK • Record a short video of your set and get instant, rep-by-rep feedback — squat, bench, deadlift, overhead press and more. • Trayner scores your form 1–10, calls out the top fixes, and flags the rep that needs the most attention. • Real measurements — depth angle, bar-path drift, knee valgus, torso angle, elbow flare — not vague advice. • Every check is saved per exercise, so you can see your trend line, your baseline, and how today compares to last session. TRAIN SMARTER • AI-generated routines built around your goal, experience, equipment, and schedule — with a weekly plan that adapts as you log. • Fast set logging with smart defaults, full history, supersets, rest timers, and one-tap re-runs. • A 580+ exercise library with demo videos, muscle maps, and how-to cues. • More than lifting — guided Yoga, Pilates, Stretching, Mobility, Rehab, and Cardio. • Strength Score, weekly volume, muscle recovery, PRs, and a training roadmap that shows where you're headed. EAT FOR YOUR GOALS • Log food by search, barcode, nutrition-label scan, or a photo of your plate — calories and macros in seconds. • AI meal plans and grocery lists that flex with your training days, plus a daily health score. • Track water, supplements, and body composition (InBody-style scans) all in one place. RECOVER + READINESS • Recovery, Strain, and Sleep insights (HRV, resting heart rate, sleep quality) so you go hard when you're fresh and back off when you're not. • Stress and Energy monitors, progress photos, and weight & measurement tracking. • Syncs with Apple Health / Health Connect for steps, sleep, and energy. ALWAYS WITH YOU • Home- and lock-screen widgets, an AI coach you can chat with, streaks, and milestone badges to keep you consistent. BUILT FOR LIFTERS Whether you're chasing your first bodyweight bench, training for a powerlifting meet, or just trying to stop your knees caving on heavy squats, Trayner gives you the eyes — and the plan — you don't have when you're alone in the gym. PRIVACY Your videos stay on your device unless you ask for a form check. Form-check uploads are processed and discarded — nothing is used to train models.
