Accessory compound

Barbell Step-Up

Trains quads first, with real work landing on glutes, hamstrings, core and more.

Muscle contribution per set

Quads1

Glutes.50

Hamstrings.20

Core.20

Calves.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.

Controlled tempo emphasises quad and glute drive without momentum; unilateral strength and stability.

Drive through whole foot; avoid pushing off back leg.

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.
