This is a seriously heart-pounding workout! I had to laugh the first time John tried it… he was breathing hard, but had just enough breath to gasp, “And I thought I was pretty fit!” The thing teaches you what your limits are, pretty quickly. ;-)

It may not look like your idea of a good time… but it is kinda fun.
