I'm going to use the bag for combinations. I have to get those combos ingrained into my brain. Not to mention the stamina benifits. Not permanently doing this, but I like to concentrate on one learning thing at a time. Quick, short punches, something many young fighters have no idea of. Basically I want to imitate Riddick Bowe in Holyfield 1, in case I have to fight a brawler who likes to have his way on the inside.
