Scavenger alternates between targeting lower body muscle groups, upper body muscle groups and then a combination of both. This is a high burn workout that can easily push this Level 3 a tad higher if you go a little faster and, in addition, go for EC. There are a lot of muscle groups that are recruited here and the alternating focus does not allow a lot of time for recovery, so you find yourself in the sweatzone pretty fast. Perfect for those days your body craves a test but you are unwilling to go up against a Level 4 workout.
Extra Credit: Keep the plank without dropping to the floor in between exercises #4 to #6.
