I have seen the step Cathe uses in sporting good stores and through the link on this site to order it. I already own the Reebok step but was thinking about getting this other step... I have tile floor and use a yoga mat under my Reebok step so it won't slip, and it seems like the step Cathe uses is more sturdy, slip resistant and maybe easier on the joints? I don't want to waste my money so if the Reebok step is just as good I'll stick with it, but I just wanted to check with the educated Cathe crowd before I made any final decisions. This forum is awesome and you all have helped me with so much! Thanks! Any and all suggestions are welcome.
