Heel slide
Keep the trunk quiet as one heel slides away.
How to do it
- Lie on your back with knees bent and feet on the mat.
- Slide one heel away only as far as your back stays comfortable.
- Return and alternate legs.
Form check
Avoid forcing your lower back flat or holding your breath.
Make it easier
Slide the heel a shorter distance.
Move within a comfortable range and keep breathing. Stop if a movement causes pain or you feel unwell. Ask a qualified trainer for help with unfamiliar equipment.
