Seated Deep Lean

Pronounced backward lean. Heavy anterior-core isometric.

On a chair or the edge of a surface. Moderate cost with a large mobility demand at the hip — the seated families expose adductor and hamstring restriction faster than any other.

Limiting capacity

Mobility limits this posture. Hip, adductor and thoracic range. Determines which positions are available and comfortable.

Intensity

What it costs, by role

Modelled intensity by role for Seated Deep Lean
Role	METs	Band	Active-minute credit
Active role	5.8	Moderate	1×
Receiving role	4.6	Moderate	1×

Light is under 3.0 METs, moderate 3.0–5.9, vigorous 6.0 and above (CDC). A session averaging at or above the vigorous line has its minutes credited at 2× in the Active Minutes ledger.

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

Seated straddle to 70° total abduction with a tall spine.

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
90/90 hip switch
Seated, rotate knees floor to floor under control. 3 x 8/side.
02
Cossack squat
Wide stance, sit to one side, other leg straight. 3 x 6/side.
03
Pallof press
Anti-rotation. Press out and hold. 3 x 10/side, 2s hold.
04
Eccentric release
Contract briefly, then lengthen over 6s. The half everyone skips. 3 x 10.
05
Zone 2 base
30–45 min conversational pace, 3–4x/week. The foundation under everything.
