Let me start off by saying that I love Cathe's strength training videos--that is how I came to buy IMAX. I am not a cardio person and definitely need to work on it. This morning confirmed this for me. After getting out of bed, which was a struggle itself, I turned on the video and sweated up a storm during the warm-up. Which, by the way, I could not do entirely successfully. At this point I should add that I have never done step. I'm sure you can envision the rest. Needless to say, I was a wee bit discouraged. And thouroughly disgusted with myself!!! I am thinking that perhaps I should take 1 interval a day and learn the choreography, since I am obviously NOT gifted in that area. Does anyone have any advice? Has anyone else experienced this similar discouragement with any of Cathe's videos--that is, watching the choreography and moves in complete amazement?
