## What is 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.

In v1:
• Powerlifting (raw IPF/WRPF)
• Powerbuilding (PL + structural work)
• Hypertrophy (PPL, Upper/Lower, Full-body)
• General strength fitness
• Turkish-first UI with English option

Not in v1 (coming later):
• Calisthenics
• Apple Watch / WearOS
• Coach dashboard

Monthly, annual, or one-time Founder's Edition (first 500 buyers) subscription. No free trial — the monthly tier is the entry price.
