This is actually a boxing technique exercise that Mike Tyson used to create his explosive angle changes. Angle bumps also happen to work your legs harder than just about any other boxing technique I’ve ever used. To do these, you’ll want to square up with a heavy bag. Then, you slip to either the right or to the left, essentially squatting down on that leg and leaning your body slightly over it. Then, using the explosive power of your legs and hips, turn and rocket your body to the side of the bag, doing your best to land in a stance you can punch out of. Try and switch sides back and forth as rapidly as you can for 3 minutes, adding in some punches if you want to practice some angle punching.
