This is at the high end of an intermediate workout. Lots of burpee style drills and a really good one for the upper arms, core and heart rate. You gotta be pretty fit to take on this one.
Incredible! This workout has had the highest calorie burn for me so far in the 30-minute range by a long shot! It got me so energized and into it that I snapped two hair ties trying to keep my hair out of my face!
