Accessory compound

Good Morning

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

Muscle contribution per set

Hamstrings1
Glutes.55
Erectors.40
Core.35

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

4down
0pause
1up
0squeeze

Extended eccentric for hamstring and glute stretch; hinge pattern with controlled tempo reduces injury risk and increases stimulus.

Soft knees, neutral spine; hinge from hips, not lumbar.

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.
