Log sets as you train, then finish with a clear summary of volume, time, sets, muscles, and exercise changes. Built for gym training: • Workout templates you can repeat • Recommended workouts from practising exercises and training type • Fast set, rep, weight, and duration logging • Warm-ups, supersets, circuits, and drop sets • Finished workout summaries with volume, time, sets, and muscle coverage • Workout history, exercise stats, and exercise history • Body measurements and progress trends • Coach tools for client sessions, templates, history, progress, and notes MuscleLab is not a social fitness feed or a calorie tracker. It is a clear training log for people who want the next workout to be easier to start and easier to understand afterward. Log workouts. Repeat what works. See progress.
