Upper-body pull

Chin-Up

Trains lats first, with real work landing on biceps, forearms, upper back and more.

Muscle contribution per set

Lats1
Biceps.40
Forearms.30
Upper Back.30
Core.25
Rear 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

Same vertical pull logic as pull-up; pause at bottom increases difficulty and scapular control.

Supinated grip; full extension at bottom if shoulder mobility allows.

How Forge progresses it

Progresses by load: +1.25kg increments, earned session by session from your rep quality.

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.
