TRAK builds your training program, logs what you eat, shows you how recovered you are, and turns every session into progress you can see. AI-BUILT WORKOUTS Tell TRAK your goal, your schedule and what you have to train with. It builds a program around your real numbers and adjusts as you go. Change the days you train, swap an exercise from the live card, or ask for a different split in plain words, and your progress comes with you. THE JOURNEY Every workout, meal and scan moves you through 12 gyms, from The Garage to The Grand Temple. Finish a gym to earn a new TRAKY and that gym's finish, then wear it on your profile. LOG SETS THAT COUNT Every set shows what you did last time and is scored against your history. Weight suggestions come with the reasoning, PRs are called the moment you hit them, and a stated max is treated as a ceiling, never a target. Your summary compares each lift with last time, and every lift has its own page with your estimated max over time. FOOD, THE FAST WAY Snap a photo, scan a barcode, say it out loud, or type "3 eggs and toast." A photo comes back as one plate you can fix in a tap, your usual foods are one tap from logging again, and Undo is always there. TRAK resolves every entry against a real food database, shows how confident it is, and matches chain restaurant orders to their own menus. Your targets come from your own data and adapt as your weight changes. YOUR RECOVERY MAP A two-sided muscle map fills in from the sets you log, so you can see what is loaded, what is ready, and what to train next. BODY SCAN, HANDS FREE Prop up your phone and TRAK checks your lighting, frames you, takes each pose on its own and talks you through it, then tracks how your muscles develop from scan to scan. Short on time? Take a quick scan. RUNS, WALKS AND EVERYTHING ELSE Cardio, HIIT, mobility, walking and sport days live in the same program as your lifts, with calories burned measured first and estimated only when they have to be. LEVELS, BADGES AND YOUR PROFILE Earn XP and level up from the training you already do. Every badge has its own medallion, and your Profile keeps your progress, collection, analytics and friends in one place. SEE THE TREND Strength progression, a PR timeline, body recomposition, and a training consistency heatmap, all built from your own logs. TRAIN WITH FRIENDS Send a friend your link and you're friends the moment they join. Every workout your friends finish lands in your feed as a live muscle map, with their PRs up front. See who is training right now and cheer them on their lock screen, put a friend's workout on your own plan, react with any Trakkie, and thank everyone who reacted in one tap. Compete on friends-only leaderboards, call out a challenge, and get a weekly rivalry recap. Share to Everyone, where people across TRAK aged 18 and over can see your posts, or keep any post to friends. Adding friends and earning badges are free.
