Crazy Chick Workout (Bodyrock.tv Inspired)

I was going to do Bodyrock.tv Crazy Monkey workout but decided in last minute to modify it a bit to give myself a bit more challenge.

Part #1: 15 minute time challenge

Do as many sets of:
10 Knee raises (on a dip station)
10 Reverse Push Ups
10 Dancing Crabs

I completed 7 sets + 10 knee raises

Part #2: 4 minute interval high knees skipping (10 sec off/20 sec on for 8 rounds)
I didn't count the skips, but I was out of breath a lot and my arms were burning from the upper body challenge from the previous workout.

Good sweat, good day!
