This is the best fitness and rehab tool to come along in years! Many years ago, I was fortunate to learn the benefits of foot and leg strengthening with 'toe yoga' and rocker board exercises from Jay Dicharry, and I've used this with my patients and running clients ever since. The MOBO Board combines the benefits of intrinsic foot strengthening, ankle/leg strengthening, and balance work all into one elegant, simple to use product. But what may seem like a simple product has quite a bit of science behind it that you won't find in typical rocker boards…the inverted toe box requires more use from the great toe, the 45 degree axis of rocking better fits the anatomical axis of the ankle, the amount of rotation fits the physiology of the foot and ankle. All that being said, nothing beats feeling the MOBO board in action. You'll obviously feel your foot and ankle working, but less obvious will be the challenge to your hip and core with all the single leg work. The exercises on moboboard.com are awesome. More than just strengthening the foot in isolation, these exercises teach you to use the foot, ankle, leg, hip and core altogether. I've felt the benefits of the board for myself and have also heard nothing but good reviews from the patients I've recommended it to and the strength training clients I work with. Whether you need to rehab foot, ankle, or leg problems, prevent them before they happen, or improve your athletic performance, the MOBO board will be a valuable asset to you!
