Logging that disappears

Say it. It's logged.

Type or speak your session the way you'd tell a training partner. The coach parses weights, reps, RPE, distances and paces — for lifts and cardio in the same breath.

See your whole training load.

Strength tonnage and cardio load on a single chart, so you can actually read the trade-off week to week. Per-muscle volume, a recovery heat map, and push/pull + quad/posterior imbalance warnings keep the plan honest.

Twelve-week arcs

A coach that holds the line.

Progression is managed for you across three blocks. At the end of each arc you re-test — an honest checkpoint — and the next arc seeds its opening loads from the numbers you actually hit, not the ones you guessed.
