I have heard of a Wii before; but until I watched the video that you shared, Greyson, I have never seen what one looks like or how they work. I can see that it would be really helpful for a person who wanted an at-home exercise program.
I have really bad balance; so I am pretty sure that I could not manage to stand on that little pad and try to do any of the things that the video shows.
I have been reading about how much rebounding can help with exercise and keeping the lymph system working right; so I got one of the mini-trampolines, and it had a bar that I can hold on to for balance. I only do basic rebounding on it, none of the more advanced exercises.
