I am looking for workout ideas that I can do at home. I took an aerobics class years ago, and I really enjoyed the step aerobics part of the workout. I have found the step at both Target and Walmart, but I can't seem to find Step Workout DVDs in stores, only online. I'd rather just go and buy it rather than have to wait for it to come in the mail. Has anyone seen them anywhere? Any recommendations for a great step workout?
