I received my high step on Christmas Eve, and it is the best purchase I have made in terms of fitness equipment since my regular Reebok step. I was using the Firm's fanny lifter (the plastic one that Wal Mart now sells ~ you place them on top of each other to make a 14" step). I just about killed myself on it trying to do Cathe's High Step Training workout. Anyway, I went ahead and purchased the high step with four of the risers. I already had four other risers that goes along with my second step. I couldn't believe how much more intensely I worked out after I got it! I was always too scared of the fanny lifter to really jump on the thing, but now I don't think twice about it with the high step. Definitely a good investment!
