Elevated Surface Step

One partner on a step or low box. Solves height mismatch cleanly.

Hips elevated and held, or one body bridged off a surface. Isometric glute and posterior-chain work — cost accumulates through sustained tension rather than through movement, which makes it deceptively expensive.

Limiting capacity

Strength limits this posture. Posterior chain and trunk endurance under load. Holds position without fatigue or compensation.

Intensity

What it costs, by role

Modelled intensity by role for Elevated Surface Step
Role	METs	Band	Active-minute credit
Active role	7.2	Vigorous	2×
Receiving role	5.0	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

Two-minute glute bridge hold with the ribs down.

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
Hip thrust
Shoulders on a bench, loaded across the hips. 4 x 8, 1s pause at lockout.
02
Single-leg glute bridge
One foot planted, other knee drawn. Level hips throughout. 3 x 8/side.
03
Hollow body hold
Lumbar pinned, ribs down. 3 x 20–30s.
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.
