ONE LIFT WENT UP. DID YOUR TRAINING? One lift can go up without telling you how the rest of your training went. Gainz puts your program at the heart of the app. Build or pick a program. Change any part of it. Log each set. Then see how you did across exercises, muscle groups, and programs over time. Gainz is for lifters who plan their own training and care about progress over years, not just days. It keeps the full story in one place, so you do not have to judge your training by one good lift. You choose what to keep, change, or try next. BUILD A PROGRAM THAT FITS YOU Build from scratch, pick a Gainz program, browse Community programs, or use one of your own. Each choice opens in the same builder, and you can edit it before you save. Choose your training days, exercises, sets, rep goals, rest times, and number of weeks. Change your program when your goals, gym, or life change. LOG EACH SET. KEEP THE FULL STORY. See today’s workout and the numbers you logged last time. Track weight, reps, and RPE. Add, remove, move, or swap exercises while you train. Add notes to your workout. Set a rest timer, pick its sound, and get an alert even when the app is closed. If your workout gets cut short, Gainz can help you pick up where you left off. You can also log offline and sync across devices when you sign in. SEE MORE THAN ONE LIFT Review past workouts, total load, sets by muscle, and how well you followed your program. Pick a time range to see what changed. Your program may change, but your history stays with you. Gainz Pro adds deeper views: • Program Performance compares two parts of a program. • Muscle Trend groups exercises for the same muscle. • Exercise Progress shows how one lift changed. • Logged RPE adds effort to each view. Each view uses the work you logged and the time range you picked. Gainz does not claim more than your data can show. MAKE GAINZ MATCH HOW YOU TRAIN Browse 300 exercises. See the muscles used, the gear you need, and how to do each one. Make custom exercises and variations so Gainz fits the way you train. Share a program by link. Import a copy you can edit. Post a program to Community. With Pro, save a program as a PDF. FREE AT THE CORE. MORE WITH PRO. Plan, train, review, and adjust for free, with no ads. Gainz Pro adds: • Advanced Review • More program slots • No limit on custom exercises and variations • Program Intelligence as you build • Program PDF export • Custom colors No streaks. No badges. No guilt. No social feed. Just your program, your log, and a clear view of your training over time. Build with care. Log the work. Let your full history guide the next change.
