Does Flex bar work?
According to a 2009 study published in the Journal of Shoulder and Elbow Surgery, continued use of tennis elbow flex bars can decrease elbow pain by 81 percent and increase strength by 72 percent.
What are flex bars good for?
FlexBars come in four resistance levels so there’s one for any workout need. The low resistances make great hand grippers and wrist strengtheners for hand grip training and wrist injury rehab. The upper levels are ideal for tennis elbow and golfer’s elbow pain relief.
