Build a 1–2 week rotation from movement patterns and see every muscle shaded by how often you train it — so nothing gets left in the grey. Frequency is counted across the whole rotation ÷ weeks (so an alternating L/U/L · U/L/U reads ~1.5×/week each).
All groups trained — 14 just under 2×/week.
Tint = primary frequency (faint → solid orange as it approaches target). The setsfigure sums each exercise's working sets × its per-set weights (a 0.5 secondary = half a set each) — so it rises with work the frequency count ignores. Set the working sets per exercise with the ± steppers. A muscle is marked fully utilised once its effective sets reach ~8/week — a defensible ceiling for a natural training heavy (6–8RM), not a hard limit.
