I just got the firm dvd's that came with the firm step, (my susan powter was getting too easy). I consider myself to be pretty coordinated, but I can't seem to keep up with it. They didn't explain the coreography at all and move from one thing to the next so quickly that I get lost. Has anyone else had this problem? I have heard great things about the results from the firm, but I get frustrated and always just throw in my susan powter...which again....is too easy. Any advice?
