Accessory compound

Kettlebell Swing

Trains glutes first, with real work landing on hamstrings, core, erectors and more.

Muscle contribution per set

Glutes1
Hamstrings.50
Core.35
Erectors.30
Front Delts.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

Xdrop fast
0pause
Xexplode
0squeeze

Explosive hip drive (X) for posterior chain power and conditioning; intent over strict seconds.

Hip snap, not arm pull; Russian or American style as prescribed. Speed and power primary.

Derived from tempo research on this movement class — Wilk M, Zając A, Tufano JJ.

How Forge progresses it

Progresses by load in +1kg steps. Accessories build the muscle that keeps the main lifts moving.

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