01 The generator
Tell it your gym.
It writes the workout.
Pick the muscles. PUMP! composes the session for the equipment you actually have — balanced, supersetted where it helps, warm-ups included.
And it’s seeded, not slot-machine: the same brief gives the same workout, until you ask for a new one. Software you can argue with, not a roulette wheel.
140+ exercises Your equipment 0 guesswork
02 The engine
Every rep decides
the next workout.
Log against the plan. The progression engine reads what actually happened — every set, every hold, every grind — and writes the next session. Loads move when they’ve earned it.
No AI roulette on your working sets. The engine is deterministic: math you could print, decisions you can trace, a history that is never rewritten.
Append-only history Computed warm-ups Earned load bumps
03 Private by architecture
No account.
No cloud. No feed.
Your training lives on your phone. Not on a server, not in a social graph, not in a quarterly engagement report. There is no login because there is nothing to log into.
Privacy here isn’t a settings toggle — it’s the architecture. The only thing PUMP! uploads is nothing.
0 accounts 0 trackers 0 excuses
04 The app
A magazine outside the workout. A tool inside it.
The manifesto
Somewhere around 2015, training apps decided to become spreadsheets. Grey grids. Cloud logins. Streaks that shame you. We went back to 1975 — when training was loud, printed in bold, and nobody’s business but yours. PUMP! is that magazine, reborn as software.
