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.

Unilateral hip thrust; tempo + top pause maximises glute work and addresses imbalances.

Drive through heel of working leg; keep hips level.

How Heatwayve progresses it

Progresses by load in +1kg steps. Accessories build the muscle that keeps the main lifts moving.

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.

Knowing the numbers is one thing; hitting them for fifty weeks is another. Open Heatwayve — it prescribes the weight, holds you to the tempo, and runs this arithmetic on every set you log so the week actually adds up.
