Answer four questions and get a ready program for the gym, dumbbells at home or just a bar.

Progression engine

Linear, double progression, 5/3/1 waves, reps to harder variations. Weights go up when every set passes; deloads when they don't.

Every set is a commit

Log a set in one tap. Your history reads like git log, each workout like git show.

Career ladder

XP for every set, ranks from Intern to 10x Lifter, and achievements with developer jokes.

Themes like your editor

Midnight and Paper for free, Vampire, Fjord, Solar and Phosphor in Pro.
