The Perils of Double-unders

When folks see me come from the gym and they say, "whoa look at that dude.  His arms are cut!" I like to think it's not because of the welts on my arms from failing at double-unders. Truth is I do have welts and double-unders are terribly painful if you fail at them. 


5 burpees, 10 renegade rows, 15 situps, 20 double-unders.   

Really simple workout.
