Standing Split Stance

One foot forward. Far more stable than it looks, and easier to sustain.

Unsupported, full body weight through the legs. The highest-cost family, and the one most limited by calf and grip endurance rather than by the larger muscles people expect.

Role	METs	Band	Active-minute credit
Active role	8.1	Vigorous	2×
Receiving role	5.6	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

Single-leg balance 30s per side with a level pelvis.

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
Farmer carry
Heavy, tall posture, 3 x 40m. Builds standing load tolerance.
02
Step-up
Tall box, drive through the top foot, no push-off. 3 x 8/side.
03
Standing calf raise
Full range, 2s pause at the top. 3 x 15.
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.
