toughness drills for offseason training

We play a game called donkey dick. We take a towel and roll it and tape it. We then have the kids get on both knees facing each other. I hold the towel in the middle with each kid putting one hand on it and I place their other hand on the towel in order to ensure that there is an equal grip. At this point I have the kids touch shoulders. The object is to get the other kid to let go of the towel (with either one hand or two hands). Anything goes except for gouging the eyes and kicking them in the groin. I did this in PE on the mats and kids love it. If you would like anymore ideas, you can email me at jhathcock@buhsd.org
