Long box

Exhale to push leg away from centre, inhale back

Muscles Worked:
Core stabilisers: Internal and external obliques, rectus abdominis, transverse abdominis for spinal stability.
Gluteals: Maximus, Medius and minimums for hip extension and leg control.
Hamstrings, Scapular stabilisers: Rhomboids, trapezius.
Hip rotators: Assist with keeping the hip slightly turned out.

Muscles Mobilised:
Hip flexors/extensors, rectus femoris, Gluteals during leg swing.
Thoracic spine: Encourages rotation and extension.

Regression:
Limit range of motion for a smaller, more manageable rotation. Forearms can rest on the box if needed.
Springs: Use fewer springs for less resistance to make the movement easier to control, carriage will be more instable.

Progression:
Bring opposite hand on belly for core challenge.
Springs: Use more springs to make lift harder, engaging the shoulders, core, and obliques.

Modification:
Side-Lying Clock for a supported, accessible variation.

Tempo:
Change: Alternate slow and quick presses. Improves control and coordination.
