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? Trade it for a better fit • Streaks that reward showing up, day after day WORKS ANYWHERE, ANSWERS TO NO ONE • Fully offline — no signal, no problem; every screen works in airplane mode • Private by design — training stays on your device, synced only when you connect to internet • Beautiful dark mode on every screen, built for early mornings and late nights • No feed, no followers, no pressure — just you and the bar KETTLE MUSCLE PRO Go deeper when you're ready: • Strength Score — one number that tracks real strength across the big lifts • Full history — 3 months, 1 year, and your entire training log (Free keeps 30 days) • Progression, PR, and muscle-volume charts across every exercise • Plateau alerts that catch a stall before it costs you a month • Full-body recovery view — see every muscle group, not just the most-loaded one • Adaptive targets tuned from your recent sessions and effort • Unlimited programs and saved plans (Free runs one) WHO IT'S FOR Chasing your first pull-up or your fourth plate, Kettle Muscle scales to you.
