PT Will Duru’s Perspective
The Mini Band Clamshell is one of the first exercises I use with clients who struggle with weak glutes or unstable hips.
It doesn’t look difficult, but when it’s performed correctly, you’ll quickly feel the side glutes working.
Strong glute medius muscles help keep your knees aligned during squats, lunges, running, and jumping. They also improve balance and reduce unnecessary stress on your hips and lower back.
I recommend including Mini Band Clamshells in every lower-body warm-up, especially if you spend long hours sitting or you’re recovering from a lower-body injury.

Coach Will’s Recommendation
Don’t rush this exercise.
The goal isn’t to lift your knee as high as possible. The goal is to keep your hips completely still while your glutes do all the work.
If you feel it in your lower back, you’re probably rotating your pelvis instead of moving from your hip.
Quality always beats quantity.
