Stand six feet away from wooden beam. Bend down, pick
up a 125-pound medicine ball and raise it to chest height. Throw ball at beam
by pushing arms straight out in front of you. Must bounce back at least three
feet, or else repeat rep. Five reps is one set. One-minute rest. Five sets.
Hackleman: "This is for punching power. Just
picking up the 125 pounds is killer, but I need him to throw it with power as
well. This primarily builds up his shoulder muscles."
