Lower-body compound

Pendulum Squat

Trains quads first, with real work landing on glutes, hamstrings, calves.

Muscle contribution per set

Quads1
Glutes.45
Hamstrings.20
Calves.10

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

Machine squat with arc path; tempo allows deep quad work with reduced spinal loading.

Feet position per machine; full controlled depth if knee health allows.

Derived from tempo research on this movement class — Schoenfeld BJ, Ogborn DI, Krieger JW.

How Forge progresses it

Progresses by load: +2.5kg the session after you earn it. The engine watches your reps and how hard the top set felt before adding.

Swap it for

Same movement pattern, same progression continuity — these are the alternatives the app offers mid-session when a rack is taken or equipment isn't there.

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