My athletic training dvd arrived and it looks so fun but unfortunately the little kids step shool I was going to substitute for a step is too small-I'm afraid I'll totally miss it when working out at a fast pase. Still looking on craigslist and ebay for a deal on a club step but not sure where I'd store it. I'm not interested in choreography, just using it for dvds similar to athletic training. So my question is, is the high step stable? I like that is has more risers so that I would never have to purchase any additional ones and the price is on the lower side for new steps? What about the circuit size steps, is the 11" depth big enough? Anyone with big feet use one, my shoes are size 10 and longer than 11" so I'm worried about the stability again. Any help would be appreciated, I can't wait to use my new dvd
