About

Chalk Strength is a 28-week, percentage-based barbell program for the squat, bench press, deadlift and overhead press. Test your maxes once. The app works out every weight, set and rep from there, across 118 sessions in eight blocks: max testing, volume, deload, density, a retest, and two capacity blocks. HOW IT WORKS • Enter or test your four one-rep maxes • Open today's workout with every weight already calculated • Tick off sets as you go, or mark a missed set and log the reps you got • The rest timer starts automatically and alerts you when time is up • Warm-ups and stretching are built into every session • Plate breakdown for your bar BUILT TO STAY OUT OF YOUR WAY • No account, no ads, no tracking • Your data stays on your iPhone and in your own iCloud • Pounds or kilograms, light or dark • Export your full history as a CSV FREE TO START The first 8 weeks (max testing, the volume block and a deload week) are free. One purchase, paid once, unlocks the remaining 20 weeks. No subscription.
