Piston Fit

Piston is not a coach that writes a training program — it's a programming system that adjusts itself as you train. Built ground-up for powerlifting + powerbuilding, with hypertrophy covered. Everything runs on RPE (Rate of Perceived Exertion). How it works: • Intake: tell Piston your PRs, injury history, your equipment (rack, bar, available plates), and your goal (powerlifting / powerbuilding / hypertrophy / maintenance). • First block: 4 weeks × 4 days, Squat-Bench-Deadlift-Bench rotation. Loads are rounded to what your plates can actually load. • Session: rate each set with RPE. Next set's load adjusts automatically (A1 rule). Three straight sessions under-performing triggers a deload suggestion (A5 rule). • Meet-prep: automatic peak block. Meet-week attempt planning, weight-cut protocol, opener-below singles. • Works offline. Gym wi-fi is unreliable — Piston logs the session locally and syncs once you're back online.
