Progress your way. Progress tracks your workouts, automates your progression, and takes the guesswork out of your training — so you can focus on lifting. WORKOUT TRACKING Log every set, rep, and weight with a clean, distraction-free interface. Built-in rest timers keep you on pace. Exercise notes keep your cues close. ADVANCED TRAINING Automatic progressive overload — set a weight increment per exercise and the app adds it after every successful session. No spreadsheets. No manual tracking. Pyramid sets — assign each set its own weight and rep target. The app sequences through automatically and the plate calculator updates for each set. Supersets — group exercises back-to-back with a live display of what's next so you never lose your place. Plate calculator — built into every exercise. Shows exactly which plates to load, updated for every set. Full exercise customisation — control weight type, sets, reps, rest time, and progression settings per exercise.
