There have been machines at the gym that I felt a little silly using for the first time. I actually had to get help on the kayak machine, and I'm pretty sure nobody has ever gone slower on the stepmill than I did my first time -- I was certain I would fall and die. Certain.

However, neither of those compare to the humiliation I imagine would accompany the use of the iGallop. Which is probably why it's something for home use, and not available in gyms.

I'm not going to lie -- I think it actually looks pretty fun. Then again, I also prefer a stability ball to an office chair. But, aside from the possible fun factor, what does it do for you?

The iGallop works your abs, hips, butt, and thighs using its zero-impact, tri-axial riding action. While most of the commercials I've seen for it show women in the position you see in the picture above, there are actually a lot of different exercises you can do, all at various speeds, to change up your routine and challenge yourself.

Have you, or anybody you know, ever tried it? If you're dying to give it a ride, you can get your own here for $299.
