Kettle Muscle

Never plan a workout again. Kettle Muscle scores your recovery with a purpose-built algorithm and picks today's session for you — the right muscles, the right volume, the right day. No spreadsheets, no guesswork, no generic templates. Open the app and lift. It gets better as you use. Built for the gym floor: log a set in two taps, keep your streak alive, and swap any exercise in a tap. Everything works offline. HOW IT WORKS • A recovery algorithm reads your recent training and fatigue, then builds a balanced session — not a one-size-fits-all template • Log a set in two taps — fast enough between sets, even with chalky hands • Smart prefill puts your next weight and reps in before you reach the bar • Automatic PRs — every record detected and celebrated the moment you hit it • Curated form cues on every movement, from an 870+ exercise library • Swap anything instantly — don't like a lift?…
