What's inside

AI Workout Generator

Tell us your goal, gear, and the time you have. TrueFitAI writes a complete, history-aware session — warm-up, main work, and cooldown — and tunes difficulty to your last ratings.

Strength Programs & Progressive Overload

Run proven templates — StrongLifts 5×5, Starting Strength, PPL, Upper/Lower, 5/3/1 BBB. The engine prescribes the exact weight every session, advances it for you, and deloads automatically when you stall, with automatic e1RM personal-record detection.

Smart Nutrition & Lean-Bulk Engine

Snap a photo or describe your meal — vision AI returns calories and macros. Your TDEE, surplus, and protein targets are calculated with Mifflin-St Jeor, then auto-adjusted from your real body-weight trend to keep your bulk lean.

AI Coach

Chat with a coach that can see your workouts, nutrition, sleep, symptoms, streaks, and goals. It uses behavioral psychology — habit stacking and identity-based motivation — across five coaching styles to keep you consistent.

Everything else you get

• Daily command center: a 0–100 health score across exercise, nutrition, sleep, hydration, supplements, and mood.
• Volume tracking: weekly hard sets per muscle graded against MEV/MAV/MRV landmarks.
• Progress & PRs: personal records, body measurements, progress photos, and streak calendars.
• Habits: custom habits, templates, heatmaps, and XP for every check-in.
• Challenges & XP: 50 levels from Beginner to Titan, auto-unlocking achievements, and community challenges.
• Health detective: log symptoms and let AI surface correlations across sleep, mood, training, and energy.
• Sleep tracking, AI health insights, and community groups.
