Bodyweight progression

Wall Sit

Trains quads first, with real work landing on glutes, core.

Muscle contribution per set

Quads1
Glutes.20
Core.15

These are the weights Forge's volume audit actually computes with — deliberately conservative, so compounds don't masquerade as full coverage. A 0.5 means a set counts as half a set for that muscle: meaningful help, not a replacement for direct work.

Tempo

Hold, don't count reps.

Isometric quad and glute hold — tempo notation not applicable.

Hold 20–60 s; back flat against wall, thighs parallel to floor or as prescribed, brace core. Breathe steadily.

General isometric training literature — holds are prescribed by duration and bracing quality, not rep tempo.

How Forge progresses it

Progresses by reps, not weight — you earn harder sets, longer holds, or extra reps rather than plates.

Train with intention. Open Forge — it prescribes the weight, watches the reps, and does this arithmetic for every set you log.
