Isometric Clamshell Exercise
Isometric Clamshell Exercise
A banded clamshell hold that isolates the glute medius with strict anti-rotation control—no cheating through the pelvis.
Muscles Targeted
Gluteus medius/minimus, deep hip rotators, and lateral hip stabilizers.
Key Benefits
- Pure lateral hip work without momentum
- Improves hip stability for single-leg mechanics
- Easy to scale by band tension and hold time
- Great drill when you need strict control
If your pelvis rolls back, the set doesn’t count—keep hips stacked.
Equipment Needed
A mini resistance band placed above the knees.
How to Perform
- Lie on your side with hips stacked and knees bent.
- Place the band above your knees.
- Open the top knee slightly and hold.
- Keep pelvis still—no rolling back.
- Maintain steady tension, then switch sides.
Programming Options
- 3–5 holds of 10–25 seconds per side
- Or 2–4 sets of 20–40 seconds per side
- Pairs well with bridges, step-ups, or running prep
Why This Variation Works
The isometric hold removes speed and momentum, making it easier to identify compensation and load the lateral hip the right way.
When to Use It
Perfect when you need glute med emphasis, better pelvic control, or a low-impact hip stability option.
Frequently Asked Questions
How high should my knee open?
Only as far as you can go without the pelvis rolling back—small is usually better.
Where should I feel this?
On the side of the hip/glute. If you feel it in the front of the hip, reduce range and slow down.
How do I make it harder?
Use a stronger band or increase hold time while keeping perfect pelvis control.
