I have fell in love with many of Cathe's strength training DVD's and thought I would try the Step workouts. I bought Step, Jump and Pump and Step Blast. However I have NEVER done any step workouts before. I thought I would start with the 31 minute premix from SB....it is very complicated!!! Although it looks like if you can do it it would be an excellent workout. What dvd's do you recommend to a newbie to step to learn the moves?
