Even at a real boxing gym against super inexperienced guys, I become a more a of a counterpuncher when guys are throwing nothing by wild bombs. If you have any skill at all, you can see them coming a mile away, slip or roll them them come back hard, even if it's just a really stiff jab. Those guys in the video are so off balance it's not even funny.

You can also do what Donny says. That works, too.
