The engine explains itself
Auto-progression runs on four transparent rules, a daily readiness check-in changes today's weights, and a deload advisor fires on named triggers. Every number it gives you carries its why, built from your own sets.
Volume you can see
The Muscle Ledger counts weekly sets per muscle against grow targets, drawn on a body heat map so lagging muscles are obvious at a glance. Mesocycle blocks ramp volume week over week — only when your recovery says you can take it.
