Cathe, I am doing one of your rotations for the first time. I noticed for two weeks you take Fri off and then the next two weeks its Wed's off. Does a person need to rotate their day off to keep the body guessing and working hard? Prior to this rotation I always took Sundays off. Also, I do a lot of step. Do I need to find other things to do one or two times a week so my body doesn't get used to step and not improve any longer? I have several of your workouts and keep rotating and changing it up but I read that you should do only one type of exercise. I love step and weight lifting and I don't want to replace it with something else. I love to exercise and I want to be the most effcient I can be. Your advice is appreciated. Thanks Vicky
