This training device helps you to exercise hard-to-reach core abdominal and oblique muscles while allowing you to improve balance and coordination without having to go to a gym. The board has a non-slip platform with raised rubber toe and heel plates for better traction, and when mounted and activated using the remote control, the board pitches and yaws at three different speeds--slow, medium, or fast--forcing your abdominal muscles to contract in order for you to keep balance, resulting in a low-impact core workout. You can also initiate a 15 minute cross-training program that shifts between the three speeds intermittently. An automatic timer shuts off the device after 15 minutes. Four non-skid rubber pads keep the board stationary while in use and will not mar hardwood surfaces. Plugs into AC. Supports 250 lbs. Remote includes one CR2032 battery. 29 1/2" L x 10" W x 14" D. (49 1/2 lbs.)
