Isolation

Mountain Climber

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

Muscle contribution per set

Core1
Front Delts.25
Quads.25
Chest.15

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.

Tempo

1down
0pause
1up
0squeeze

Cyclical core movement held at plank; the demand is bracing under a fast alternating leg drive, so the tempo stays quick and even.

Hips level, no piking; drive the knees, keep the shoulders stacked.

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.
