RepStack: Gym Workout Tracker

RepStack is a gym workout tracker that tells you exactly what to lift today. Log sets fast, see what you did last time, and let the progression engine update your weights, reps, deloads, PRs, and Strength Score automatically.

WHY LIFTERS USE REPSTACK

- Know your next weight and rep target before every set
- Adapt today's workout when the gym is busy: swap days, replace exercises, edit sets and reps, or apply changes every week
- Track progressive overload without spreadsheets
- Log real strength training details: warmups, working sets, AMRAPs, drop sets, failure sets, RPE, RIR, and rest times
- Use the plate calculator to load barbells faster in kg or lbs
- Import programs from text, XLSX, CSV, or build your own split
- Search 873 exercises with images, muscle filters, and offline access
- See PRs, e1RM trends, volume, Workout Rewind, What-If Projections, and Strength Score

BUILT FOR THE GYM
