Day 8 Plyometric Cardio Circuit

Today was the 3rd time doing this workout and I still was having difficulty. I'm hoping that by next week I will be able to do it better. The most difficult exercises for me are the mountain climbers, ski downs, ski abs and in-and-0uts. My legs and arms just feel so weak by the 3rd set and I am barely able to finish out the exercises. Lookin forward to Friday's workout which is today's workout PLUS Cardio Abs.
