I found the high step workouts are great for the hamstrings. You will be sore but they do the job. I started with a riser or two less than they use in the videos and slowly started adding. I'm up to 5 and I think that's as high as I can go because I'm short with short legs. The workout I started with on the intermediate rotation was Pyramid Lower Body. The next workout with the high step was Push Pull but I didn't like it as well as the PLB because it seemed kind of rushed. I liked the pace of the PLB better and I could really feel the hamstrings working.
