Upper-body pull

Chest-Supported DB Row

Trains upper back first, with real work landing on biceps, lats, rear delts and more.

Biceps.40

Rear Delts.35

Traps.25

Forearms.20

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.

Supported position allows stricter tempo and heavier loading on lats/rhomboids; pause removes momentum.

How Heatwayve progresses it

Progresses by load: +1.25kg increments, earned session by session from your rep quality.

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.
