Mobility

Clam Shell

The Clam Shell is a simple yet effective exercise for your glutes (buttocks) and hips. The movement involves lying on your side and opening and closing your legs like a clamshell, which helps improve your hip stability and flexibility. This exercise is particularly good for those wanting to strengthen their glutes, improve hip mobility, or as part of a rehab routine after an injury.
