We have a free standing heavy bag for my youngest son's kickboxing in the basement. He is 11 and will be starting pee wee football this spring. We have been using it for me to teach him block and tackle technique. After watching Jarvis Jones make an incredibly sloppy tackle attempt he walks up to the bag and said, "Dad why did 95 just do this" and body checks the bag. I said son tonight is 95's best game of the season.
