The Slide Reebok Board is a balanced program offering a low-impact, highly effective lateral movement workout easily customized for all fitness levels and performance needs. It's a safe method of cardiovascular and athletic conditioning that's used by Olympic decathletes, Olympic figure skaters, and hockey players as well as those needing rehabilitation. The slide board uses side-to-side motion to train the muscles of the lower body, and to protect and rehabilitate the joints of the hips, knees, and ankles, while promoting overall fitness. The board is ready to use: just roll it out, put the Slide Reebok Socks over your athletic shoes, and get ready to go! And it's easy to store; just roll it up! The Slide Reebok comes with a workout booklet.
