The Body Bar Flex® (Patent Pending) uses the same easy grip rubber as the Original Body Bar, but contains a fiberglass rod which allows the bar to flex. Perfect for balance, flexibility and resistance training. The Body Bar Flex® is a graceful and easy-to-use tool. Incorporating standing, seated and floor exercises, individuals can tone and stretch all major muscle groups. Perfect for those just beginning an exercise program and for those hoping to increase range of motion while building strength. You'll build flexibility and balance at the same time. Using controlled movement, you will strengthen core, back and abdominal muscles which will stabilize your body and give you the functional range of motion and balance needed for everyday movement. It's a perfect tool for anyone who wants to stay active, strong and independent.
