I use to do double step back in the early 90's when I belonged to a gym and I have to say it was so much fun. I happen to have 2 steps, (1) my original cheap one, and then I got a better one from Reebok. They may not be the same hight, I never put them side by side before, but maybe they all have the same step hights. One would think so. I thought I'd keep the old one incase a friend wanted to do step with me one day...never did yet, but hey, you never know.
We just bought a new house (closing in Aug) and I will have a 2 car garage for my gym. So I'd have lots of room.
I think there will be some people who would love this idea, and some that just wont, but I think there will be enough to justify doing the dvd. That's my take.
