Back in the gym today and everyone is a little broke off. My first question as I walked through the door was, “Whose hamstrings are sore?” Everyone raised their hands.
“Trampolines!” I shouted. “Let’s work it out!”
Today after the warm ups we will begin the explosive drills, but only after our box jumps test. I use the box jumps as a way to thoroughly warm up the body for the explosive movements later. I have three large sturdy boxes that are 13 inches high and 29 inches wide. I had them enforced at each corner to handle 400 pound linemen easily. The tops are layered with rubber matting so no one slips. I will give each group 90 seconds to do lateral jumps onto and then off the box, back and forth. Before we start I tell them that 80 jumps in 90 seconds tells me you are in great shape. Then I tell them of a high school kid preparing for college at Cal by the name of Kyle Kirst, who did 108 jumps in 90 seconds….then I blow the whistle.
No one went over 70 jumps. After the first time through, we reduce the time to 60 seconds. I then tell them Kyle’s record…88 jumps, and blow the whistle. Demetrius pulls off 62. After that set, we go to 30 seconds and this is where I make it mandatory that everyone get at least 30! My lowest was 28. I think we are ready to jump.
