Isolation

Hang Power Clean

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

Muscle contribution per set

Hamstrings1
Glutes.60
Core.40
Forearms.35
Traps.30
Quads.25
Front Delts.25
Calves.20
Erectors.20
Upper Back.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

1down
0pause
Xexplode
0squeeze

Explosive concentric from hang position; minimal pauses for power and rate of force development.

Triple extension focus; catch in power position. Speed over seconds.

How Forge progresses it

Progresses by load in +0.5kg steps. Isolation work is where the honest-volume ledger pays off — compounds alone don't cover it.

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