An exercise gadget from iJoy is the Board Trainer which lets you work your abdominal and oblique muscle snow board style.
You can see a video of it in use here and it does look kind of fun though no replacement for the real thing. The board trainer is available from Hammacher for $479.95 or Amazon at $295.00, hmm tricky choice.
The Core Muscle Balance Board Trainer.
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 speedsslow, medium, or fastforcing 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 mark hardwood surfaces.
