APPROVED BY THE BEST ATHLETES

Considered by many to be the best baseball player in the world, Ronald Acuna Jr tore his ACL in 2021 and was introduced by his doctors to CastleFlexx. Nine months later he returned to the field and was voted an All Star for the third time by the fans. In 2022, Acuna Jr. won the MLB comeback player of the year award.

Roll Up for Easy Access

The device's slim profile allows you to display to fit with your home decor.

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.

What the Professionals Say

Testimonials

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.

Dr. Rachel Skolnick

DC, BS. Chiropracter

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!

T Delgado

Personal Trainer

Unlike isolated stretching, Castleflexx stretches the entire posterior chain of the lower limb making it THE functional stretching tool on the market.”

Dr. Hamid Sadri
