RepCheck: Workout Programs

Rep it, Check it. RepCheck is a strength training tracker and gym log built for lifters who follow structured barbell programs for powerlifting and weightlifting. It takes popular community spreadsheets — like 531, nSuns, and GZCLP — and turns them into a fully functional workout app. No more spreadsheets. Set your max, and RepCheck handles the rest: percentage-based weight calculations, set-by-set tracking, and automatic progression as you advance through your program. BUILT-IN PROGRAMS Popular strength programs based on community spreadsheets, ready to run: - Wendler 5/3/1 (BBB, FSL, Joker, Beginners, and more) - nSuns 5/3/1 - GZCLP - Texas Method - Madcow 5x5 - Reddit PPL - TSA Programs - StrongLifts 5x5 Each training program comes with structured weeks, days, and percentage-based sets. All programs can be fully customized to fit your needs. MAX SYSTEM & WEIGHT CALCULATION RepCheck calculates your working weights based on a flexible max system. Define your own max entries — 1RM, Training Max, 3RM, or anything else — with a custom name and description. Multiple exercises can reference the same max. For main exercises, every set is calculated as a percentage of your max and rounded to your plate setup. For accessory exercises, you set absolute weights directly. When you complete an increment week, your max updates automatically, keeping your progressive overload on track without manual adjustments. PROGRAM BUILDER Go beyond the built-in programs. Build your own custom routines with full control: - Weeks, days, and exercises - Exercise types: Main (percentage-based) and Accessory (absolute weight) - Sections per exercise — for main exercises, sections group your sets like Warm-up, Main Sets, and Back-off Sets. For accessory exercises, the exercise itself acts as a category like Push or Pull, with sections for each movement like Dumbbell Press or Lat Pulldown. - Set types: Standard, AMRAP, and RPE - Custom rest time per set - Increment rules for automatic progression Design your program once, then just follow it. Duplicate programs, weeks, days & exercises to quickly build variations. CYCLE & NAVIGATION Programs with repeating cycles automatically advance to the next cycle after the final week. Navigate freely between cycles, weeks, and days — see exactly what weights you'll be lifting at any point in the program.
