I just finished this workout with the bonus abs on the step. The step combos were all doable with easy to remember steps so I didn't get confused on any of that but I did have to modify some of the blasts. Like blast #1, my feet just will not do that squat on step and off step. Don't know why, even to this day, I still cannot do power turning squats on the step. I also modified the #2 blast only because I wanted to try if on the floor first, then on the second round, I used just the platform and it went pretty well. I also did not do the heel clicks. Instead, I just used 3lb dumbbells and just kept doing the knee lift straddle, just like in her Low Impact Sweat from ICE. Finally the last blast, I didn't do the burpee, I did a plyo jack. I had sweat dripping off my nose by combo 6 or 7, lost track. The abs were great. I don't know which one I like better, loved them both. I might make a blender of the 2 abs together, something for me to think about. Great job Cathe!!!
