Ab Wheel
Trains core first, with real work landing on lats, front delts.
Muscle contribution per set
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
Extended eccentric rollout maximises anti-extension demand and core lengthened-position tension; controlled return prevents lumbar compensation.
Scale with band assistance or knee variation if full ROM lost.

How Heatwayve progresses it
Progresses by reps, not weight — you earn harder sets, longer holds, or extra reps rather than plates.
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.
