Isolation

Rear Delt Row

Trains rear delts first, with real work landing on upper back, traps, biceps.

Muscle contribution per set

Rear Delts1
Upper Back.50
Traps.25
Biceps.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.

Chest-supported row with the elbows flared; a controlled lowering and a held top keep the rear delts, not momentum, moving the load.

Chest on an incline bench; elbows out at about 60 to 75 degrees, pull to the lower chest, hold a beat at the top.

How Heatwayve progresses it

Progresses by load in +0.5kg steps, or one rung of the stack. Isolation work is where the honest-volume ledger pays off — compounds alone don't cover it.

Swap it for

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.
