"This 14 minute video is something that I hesitated to record because pro athletes and celebs pay a LOT of money for me to teach them this specific routine. It helps them address the ROOT cause of major lower back, hip and knee issues. Then we decided that anyone who is a customer of The Flexx Lab deserves full access to me and my knowledge so here it is...

Enjoy it. This routine changed my life and got me off painkillers and most importantly, out of bed."

This clip was NOT rehearsed with Head Instructor Sydnee- She experiences this for the first time on camera - Her reactions are authentic.
