Heel First

When using the CastleFlexx make sure you position it so that your heel is placed in the hole, with the canvas stretching over your foot and the front of your leg.

Correct Form

You can stretch while sitting or lying down. Keep your neck and shoulders relaxed and choose either an under or overhanded grip based on your comfort. Pull back very gently as the stretch sleeve has no elasticity.

The CastleFlexx is a great tool for hip mobility, hamstring tightness, tendinosis and plantar fasciitis. It's one of the best stretching devices out on the market today! We use it with all of our patients here to help improve their quality and treatment plans.

The bar itself is a one of a kind design. It puts zero stress on your patients back, neck or shoulders. You are able to just isolate the muscles you are trying to stretch. It is the best hamstring stretch one could ever get!
