The CastleFlexx

The CastleFlexx was invented by Dan Castle to address the root cause of common chronic pain issues people deal with on a regular basis.

While most devices treat the symptoms, this device addresses the ROOT cause of lower back pain, hip tightness, plantar fasciitis, shoulder impingement and three dozen other serious injuries.

Composed of 100% eco friendly materials, the CastleFlexx includes a weighted mobility bar with a 2lb interchangeable magnetic weight that acts as both stretch assist and allows for full body strengthening exercises.

With 3 USPTO patents issues for design and utility, this device is literally one of a kind and used today by professional teams and athletes across the PGA, NFL, NHL, MLB and NBA.

In 2022 CastleFlexx signed Ronald Acuna Jr. to a multiyear exclusive deal after he used it for his ACL rehab eventually winning the MLB Comeback Player of the Year 2022.

Features that are unique to the CastleFlexx are the ability to pull your toes into complete and even dorsiflexion as well as a stress free grip.

Our goal for this production with ABD is to show that good design and high quality devices can both look great and help you feel great again.
