Lie on your back, knees over hips. Slowly reach one heel away while keeping your trunk quiet and breathing normally.
Set up before the first rep
Clear your training space, check that equipment and supports are stable, and practise the movement without a challenging load. A short practice set helps you decide whether this variation feels suitable today.
Move with control
Lie on your back, knees over hips. Slowly reach one heel away while keeping your trunk quiet and breathing normally. Keep the first set easy enough that you can pay attention to that cue. Breathe through the movement and pause if you lose control of the position.
A shorter comfortable range can be a useful starting point. Sharp pain, dizziness or unusual symptoms are reasons to stop, not signals to push through.
Make it easier
Move one heel a short distance while arms stay down. Change one thing at a time so you can tell whether the adjustment helps. If symptoms persist, ask a qualified professional for an individual assessment.
Use it in a session
Our template uses 6–10 / side as an example target, with 1–2 working sets to start. Keep a few controlled repetitions in reserve. This is an editorial starting point, not a universal dose for strength or muscle growth.
Record the load and completed repetitions in your log. For time-based carries, record seconds instead. Increase the challenge only when the current version feels repeatable with good control.

MOVEMENT, EXPLAINED
Where it works.
Primary
- Abdominals
- Side trunk
The focus is resisting trunk movement while the limbs move. Hip flexors also contribute but are not shown as a surface region.
