We built Gainr because we were tired of generic workout plans. Cookie-cutter programs don't account for your schedule, your equipment, or the week where everything goes sideways. So we built a coach that does.
What is Gainr?
Gainr is an AI strength-training coach and workout log for iOS and Android, with an Apple Watch app for logging from your wrist. Its Coach builds your training week around your goals, the days you can train, how long your sessions are, the equipment you have, and the workouts you've already logged. Then it helps you follow the plan, and change it when life gets in the way.
The workout log is free to use, so your sets, PRs, and progress charts are yours whether or not you subscribe.
How It Works
- Tell Coach about yourself. Your goal, experience, schedule, session length, and available equipment.
- Get your week. Coach builds a weekly plan and shows you today's session.
- Train and log. Record weight, reps, timed sets, and reps in reserve. Mark warm-up sets, and see the plates to load for barbell lifts.
- Adjust as you go. Refresh next week, move or swap a session, skip a day, or ask the coach in chat why something is in your plan or how to change it.
- Watch your progress. Gainr records personal records as you log and charts every exercise. Training balance insights show which muscle groups you've been training and which you've neglected.
Coach uses your recent workouts and training history when it plans, so the more you log, the more your plan reflects what you've actually done.
Train From Your Wrist
With Gainr on Apple Watch, you can log sets, get rest alerts, and see live heart rate and calories without reaching for your phone. Watch workouts are saved to Apple Health. When you finish a workout or set a new PR, you can share it as a card with your stats, heart rate, and calories.
Beyond the Weekly Plan
You can also build your own workouts and programs, or have Gainr's AI generate them. Generated programs run 4, 8, or 12 weeks at 3 to 6 sessions per week, with push/pull/legs, upper/lower, full body, or bro split options.
