Newbie here: I'm struggling with people who are moving straight back after an exchange. Our coach always tells us not to run straight back, and I can see why; you look completely off balance and can't attack while running away. When I spar, especially with other new guys, I see a lot of them move backwards and look very vulnerable. The problem is that I don't know how to chase them down and keep a solid footing to throw a strike at the same time. I end up doing the Forrest Griffin 1-2-1 charge, and I feel like I'm even more open and off balance than the guy I'm chasing. Any tips?
