Bar Hang
Trains forearms first, with real work landing on lats, traps, core.
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
Hold, don't count reps.
Isometric hold — prescribed by duration and grip quality, not rep tempo.
Dead hang from the bar, shoulders active not slack. Time the set.
Measured directly for this movement.
- General isometric training literature — holds are prescribed by duration and bracing quality, not rep tempo.
How Heatwayve progresses it
Progresses by load in +0.5kg steps. Isolation work is where the honest-volume ledger pays off — compounds alone don't cover it.
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.
