The step taps where you straddle the step alternate tapping a foot on top. I absolutely cannot get the timing right on this. I think I may be concentrating on putting my weight on the wrong leg. Do you have any suggestions? The power squats as well I just can't seem to get either. I may just not be strong enough (I'm nowhere near as fit as you or your crew but I did get through Crossfire) Any advice for me on those. thank you for your great work and fantastic productions-you are miles away from other workout DVDs. You have spoiled me as I find I'm just not satisfied with any other instructor.
