Upper-body pull

Inverted Row

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

Muscle contribution per set

Lats.45
Biceps.40
Rear Delts.35
Forearms.20
Core.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.

Tempo

Horizontal pull with an end-range hold; the pause at the top is where scapular retraction actually earns the set when load is fixed.

Table edge or bar; squeeze shoulder blades at the top, body straight throughout.

Derived from tempo research on this movement class.

How Heatwayve progresses it

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

Train with intention. Open Heatwayve — it prescribes the weight, watches the reps, and does this arithmetic for every set you log.
