About Us

How It Started

“I appreciate the skill of massage, Chiro, PT and stretch therapists but it gets very expensive for in person sessions and they would often recommend that on my own time I stretch my legs and strengthen my core to really deal with the root cause of my lower back pain. But there was no device that could do both. CastleFlexx changed my life. I’ve stopped thinking about my back all day. I want everyone to feel this good.”
