So, I did some sparring last night and basically got my *** handed to me by the other students. Thinking back over it, my main issue right now is my guard. When I'm attacking my guard is solid and I'm usually very good at blocking the first strike that comes my way. The problem is that after I've blocked the first strike, I leave my hand in the position that I blocked with instead of returning to my guard position. This leaves me completely open to any follow-up attacks that come in. Do you guys know of any specific exercises or drills that can help me train my guard better? Or is this just a matter of training and being aware of what my hands are doing all the time?
