Read full description
Metal Strength is a workout tracker, gym log and workout planner for weightlifting and strength training, at the gym or at home. Follow one of 1,300+ workout plans or build your own, log every set, rep and weight as you train, and let Metal AI show you what to lift next time. LOG EVERY WORKOUT • Tick off sets, reps and weight as you lift. Finishing a workout saves it, even with no signal • A rest timer starts on its own after each set and tells you when it is over • Last session's numbers sit next to every set, so you always know what to beat • Warm-up sets, drop sets, supersets, set notes and RPE (how hard a set felt) • Timed sets for planks, cardio and stretches, with a full-screen stopwatch • Swap an exercise mid-workout for one that trains the same muscles • Your live workout in the notification shade, with controls • kg or lb, switch at any time 1,300+ WORKOUT PLANS AND PROGRAMS • Build muscle, get stronger, burn fat, get lean, plans for women, and sport plans for football, basketball, boxing, MMA, running, swimming and tennis • Filter by goal, days per week, level from beginner to advanced, and equipment: a full gym, dumbbells, barbells, kettlebells, machines or no equipment at home • Sets and reps in every plan follow published training research • Up next: the app opens on your next workout, with the week as a checklist. Skip a day and the plan moves with you • Not sure where to start? Answer a few questions and get a suggested plan BUILD YOUR OWN WORKOUT PLAN • Tap a muscle on the body map and pick the exercises that train it • Build it one day at a time, in any split: push/pull/legs, upper/lower, full body • Quick workout: pick today's muscles and start right away • Save your plans and run them week after week METAL AI TRAINING ANALYSIS • One tap analyses your saved workouts on your phone. Nothing is sent anywhere • A training score and the mistakes holding you back, with the research behind each fix • The weight and reps to aim for next session on your key lifts: progressive overload, planned for you TRACK YOUR PROGRESS • Charts for every lift, your weekly volume and your personal records (PRs) • Your workout log by day, streaks and badges you earn by showing up • A muscle recovery map that shows what is ready to train today • Muscle ranks that compare each muscle with strength standards for your age, bodyweight and sex • Progress photos, so you see the change and not just the numbers 891 EXERCISES WITH VIDEO • A video for every exercise, with the muscles it works and how to do it • Search the exercise library by name or by muscle • Works offline: the videos are on your phone, so a gym with no signal is no problem CALCULATORS AND GUIDES • One-rep max (1RM) calculator and strength level • Macro calculator and body fat calculator • Training guides for lifters, inside the app TRAIN WITH FRIENDS • Add friends with a QR code and compare ranks, training focus and badges • You choose what each friend sees.
