Ha! I do recognize the ab wheel, and am familiar with its tortures!
Since I started this Bootcamp, I have used all different kinds of workout equipment that, until this point, I had only seen on The Biggest Loser. The ab wheel is one. Those huge ropes that they fling around with such abandon? Yeah, those are really heavy.
The most challenging piece of equipment, I don't even know what to call it. Suspended something or others? They have hard handles for you to grip and do pull-ups or suspended push-ups and more (so much more!) or soft handles that hang down from the hard handles for you to shove the front half of your feet in there and perform various excruciating moves, all from a suspended plank position. Here's something close to what I'm talking about:
Finally, I can also tell you that I know that this thing is called a Prowler Sled, and it makes my thighs burn while pushing and pulling it. Then I can barely walk for a day after a workout involving the Prowler Sled.
I had no idea Bootcamp would be such an educational experience. And I thought I was just going for the workout!
