I did BM2 on Wednesday, but was not able to do the entire workout due to time. I skipped the UB section. I am anxious to the entire workout again this weekend. I did the workout on a 6 inch step and probably will until I master all the moves. The fact that there is a lot of high intensity and high impact moves also plays a factor in that decision, along with the fact that I am not supposed to be doing any high impact due to my recently diagnosed plantar fasciitis. The choreogrpahy wasn't that hard to learn, except for that reverse turn thing in combo #3, I believe. The cardio leg blasts were good, but could've been a bit tougher, IMO. I liked the ab section all right, but will admit to being very intimidated by those rocket thrust things. I don't have the best lower back, so I was a bit scared to do all of them. I am hopeful I will get this workout down soon and know I will have a blast everytime I do it. Cathe's enthusiasm and spirit is so uplifting and encouraging.
