Sliding Leg Curl

Trains hamstrings first, with real work landing on glutes, core.

Muscle contribution per set

Hamstrings1
Glutes.40
Core.30

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.

Hamstring curl under a bridge hold; the slow eccentric is the whole stimulus at bodyweight, per tempo-hypertrophy findings.

Heels on a towel, hips up the whole set; extend slowly, curl back under control.

Derived from tempo research on this movement class.

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.

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