Isolation

Resistance Band Crossover

Trains chest first, with real work landing on front delts.

Muscle contribution per set

Front Delts.20

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

Band fly variation; tempo keeps constant tension and prevents momentum.

Cross hands at midline; controlled return.

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.
