There are two videos. Lol. Press the little arrow on the right to see his son in a baseballcap hitting pads.
Serious question. Do steroids help increase your speed too? He is pretty sharp for a man in his 40s.
If you don't see a correlation, look at other fighters when they were 42 like chuck liddell.
As other people are saying, the heavy bag isn't mobile. Another reason is weight distribution and center of gravity. If you leg kick a heavy bag, for example, you feel like a god damn boss. Throw a hook or uppercut at it, you're met back with 50-100 lbs of reverse force reaction on your kicks and punches. Your hits feel like a cement block, you think you're the next George Foreman.Can someone with more knowledge than I please explain why guys hit those type of pads instead of just working the heavy bag?
It seems like his son is doing most of the striking with the mitts.
