Bodyweight progression

Ab Wheel

Trains core first, with real work landing on lats, front delts.

Muscle contribution per set

Core1
Lats.20
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

0pause
2up
0squeeze

Extended eccentric rollout maximises anti-extension demand and core lengthened-position tension; controlled return prevents lumbar compensation.

Scale with band assistance or knee variation if full ROM lost.

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.
