Isolation

Chair Dip

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

These are the weights Heatwayve'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.

Shoulder-extended press; controlled eccentric with the shoulder in a vulnerable position, depth limited by comfort.

Hands on a chair edge; stop when the upper arm is parallel, no deeper.

Derived from tempo research on this movement class.

How Heatwayve 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 Heatwayve — it prescribes the weight, watches the reps, and does this arithmetic for every set you log.
