Lift smarter with an AI gym tracker that understands your training, your recovery, and your next PR. GainMatrix is an all-in-one strength training companion that logs your workouts, coaches you with AI, tracks your recovery, and projects your future progress so you can stay consistent, avoid plateaus, and keep breaking records. AI PERSONAL COACH - Ask questions mid-workout about form, technique, or how to progress your lifts. - Get tailored plans whether your goal is strength, muscle gain, fat loss, or endurance. - Training adapts to you based on your real workout history, not generic one-size-fits-all templates. - Learn when to add weight, add sets, or change exercises with clear explanations.

RECOVERY STATUS - Know when to push heavy and when to back off before you burn out. - Track recovery using training load, rest days, recent intensity, and your own feedback. - Get early warnings when you are trending toward overtraining or under-recovering. - Reduce nagging fatigue and plateaus by balancing stress and recovery more intelligently. WORKOUT LOGGING - Log sets, reps, and weight in seconds so you can focus on lifting, not typing. - Automatically detect new PRs for 1 rep, rep ranges, and volume. - Use the built-in rest timer so you never lose track between sets. - Quickly repeat or tweak past workouts from your history. - Choose from 300+ exercises with clear names and categories, or add your own.

GAMIFICATION AND MOTIVATION - Progress through a 16-level system that reflects real training effort. - Earn XP automatically for every completed workout and exercise. - Maintain streaks to build consistency and avoid falling off track. - Take on weekly challenges and unlock achievements and badges that reward long-term effort. ADVANCED ANALYTICS - See total workouts, sets, reps, and volume so you understand your true workload. - Track body measurements like weight, waist, or arm size and see clear trends over time. - Connect the dots between training volume, recovery, and results. - Export your data for your own spreadsheets, analysis, or coaching.

Perfect for: - Lifters who want to see real progression over months and years, not just single workouts. - Anyone who needs structure, accountability, and feedback instead of guesswork. - Beginners who want clear guidance on what to do next and how to do it safely. Start free and turn every workout into measurable progress. Questions? support@gainmatrix.app Terms of Use: https://gainmatrix.app/terms Privacy Policy: https://gainmatrix.app/privacy

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.
