I have trouble hitting a combination of more than 2-3 punches in sparring. I'm short guy with even shorter arms for my height. Whenever I throw a combination, for example a 1-2-left hook head-lefthook body, I would hit my partner with the jab and the cross with maybe the left hook, but by the time I throw the fourth punch, he's out of range because he obviously moves out of the way. So I always throw 2 or 3 punches then I'll miss. Unless the guy's an infighter who comes at me but for some reason most of the guys I spar are boxers. This happens particularly with body punches. I find it harder to move while throwing body punches since I have to bend my legs to lower elevation. It is harder to throw punches while moving your feet at the same time anyway. The only way I can get off longer combos is when I have my opponent on the ropes. I also have a habit of not throwing because I don't think the punch is gonna land. After pondering I figure I have work on: Foot work: I need to step in more to compensate for my short arms and my opponent moving out of the way. Hand speed: Fast punches can hit the guy before he can move out of the way. Bigger combos: The more I punch the more I have a chance of hitting something. Now, the question is, how to work this shit? That's my question. Any suggestions? There are a couple things I am currently working on. There are a few very small and light weight heavybags at my gym. These things go flying everywhere after you graze it a few times so you have to chase it around. I'm working on this bad more because it makes me keep moving my feet. I'm practicing hitting it while moving and its hard as hell because my shorts arms miss so much. When working the heavy bag or shadowboxing, I practice endless combinations. Combinations that have 10 or more punches. I'll sometimes try to punch the bag for a whole round without a break in the combo. I'm hoping this will supply me with more firepower. I'm also working on throwing as fast as I can to give myself of throwing fast. Oh yeah by the way, this is boxing.
