21M Workout

A new workout every time. No planning, no equipment, no phone in your hand. Smart Workout builds you a fresh full-body circuit the moment you press START. Pick a difficulty, pick your rest, and go — the app calls out every move out loud so your phone can sit on the floor while you work. HOW IT WORKS Every workout is one 12-move circuit, run three times through. The circuit rotates Total Body → Lower Body → Upper Body → Core, three times over, so nothing gets overworked and nothing gets skipped. Moves are 30 seconds each with 5, 10, or 15 seconds of rest between them — about 21 to 24 minutes door to door. Moves are drawn fresh each time from a library of 72, so you'll rarely get the same session twice. BODYWEIGHT ONLY No dumbbells, no bands, no mat required. A chair is handy for a handful of moves and that's it. Works in a bedroom, a hotel room, or a patch of grass. NO ACCOUNT. NO ADS. NO TRACKING. There's no sign-up, no subscription prompt, and nothing to scroll past. Open the app, press START, be done in 21 minutes.
