Hi Amy - I posted this in Open Discussion and thought I would put it here as well. I too was most anticipating this workout! I was not disappointed. ;-)
Well I did Kick Max yesterday morning, without the leg conditioning drills at the end (don't have the time in the morning). It was about a 50 minute workout - perfect length for my morning workouts. I have been doing KPC twice a week to get ready for this and I thought it would knock my socks off, but apparently I really WAS ready for it! Don't get me wrong - it's a toughie! New moves put into a new order definitely got me winded and my heartrate up. However, I would say that this workout rivals KPC in it's intensity, but one is not more intense than the other. Just my opinion.
Both have something that the other doesn't and I really think they will be great in a rotation together. Again, I did NOT do the leg conditioning drills, so I guess I'm really commenting more on the cardio portion of the workout.
Oh, and one more thing I'm SORE this morning, in my hamstrings and upper back especially. Feels nice.
