TheraBand Flex Bar
The TheraBand FlexBar is recommended for rehabilitation of tennis elbow. It is also useful for preventative strength training for the wrist and elbow muscles used in striking a tennis ball. The use of a FlexBar for treatment of tennis elbow was first reported in 2009 at the annual meeting of the American Orthopedic Society for Sports Medicine. Unlike a lot of other tennis training devices, there are solid clinical trials behind the marketing claims. If you can get past the fact that it looks like an oversized licorice stick, the FlexBar might be for you.
