Kneeling Reverse Lean

Leaning back from the knees. Heavy anterior-chain isometric; build to it.

Upright or hinged over the knees. Glute and anterior-chain dominant, with a real demand on hip-flexor length — short hip flexors are what make this family feel hard for most people.

Estimates, not measurements

Every energy figure here is a modelled estimate, not a measurement. No study has measured cost position by position — the measured quantity is the session average (6.0 METs for men, 5.6 for women, Frappier 2013). These values distribute around that anchor by mechanical demand.

kcal = METs × 3.5 × bodyweight(kg) ÷ 200 × minutes (ACSM)

Values scale linearly with your own mass. If a position causes pain rather than effort, stop and see a clinician.

Mobility gate

Tall kneeling with a neutral pelvis and no lumbar compensation.

Clear the gate before adding load or duration here. If range is the thing standing in the way, Open Hips is the block that builds it.

Prescribed preparation

01
Couch stretch
Rear foot up a wall, pelvis tucked. 3 x 45s/side.
02
Reverse lunge
Step back, front shin vertical. 3 x 10/side.
03
Bird dog
Opposite arm and leg, no hip rotation. 3 x 8/side.
04
Eccentric release
Contract briefly, then lengthen over 6s. The half everyone skips. 3 x 10.
05
Tempo intervals
6 x 90s hard / 90s easy. Trains the surge capacity SQ rewards.
