I belong to a martial arts club which is based out of a community center - therefore we only meet once per week and we do alot of sparring. Well, I'm the newbie and my sensei took me aside last night to help me learn the ropes of sparring. I need practice though to have good reaction time. Any tips for practicing / training sparring alone??? I cannot think of anything except letting the heavy bag come back at me after I hit or kick it int he first place. any ideas would be appreciated.
