Clamshells Done Right for Corrective Exercise to Protect the Knees

I think you’ll like this!

Clamshells are a great corrective exercise to strengthen the posterior fibers of glute medius. The glue medius is often weak, especially when a client/patient/athlete’s knees move inward (adduct) during an overhead or single leg squat.

I observed most trainers and clients performing this exercise incorrectly. They allow compensations such as the hips opening up to make up for tight adductors or the lumbar spine moving laterally as a result of weak core stabilizers.

Here is a helpful tip for this popular corrective exercise that will help you (or your clients/patients/athletes) to emphasize the posterior fibers of glute medius. Please comment and let me know what you think!

    Very helpful clip on clamshells. I’ve always taught them avoiding too much opening in the hip, so am happy to be on board with that concept, but was saying “duh” to myself when you demonstrated the use of the pad to allign the body. Then, doing the same without the pad is excellent! Thanks. Love these fragments of great advice. Keep sharing! linda

    Awesome exercise. Clam shells are a hidden gem in an arsenal of great exercises. Unfortunately many people do perform this incorrectly. Focusing on form greatly enhances the effectiveness of training Great Tips. Good Demo.
