MuscleLab is a focused strength training tracker for people who want to train consistently and see real progress over time. Start from a saved template, generate a workout from exercises you practise, or begin with an empty session. 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.
