I've been studying Taekwondo for a couple of years now - typically going 3 nights a week for roughly 1 to 1.5 hours each night. Recently I've started to ramp up my effort and trying to go more often and to stay longer. Ideally, I would like to go 4 nights a week for about 1.5 hours a night and then get in an extra practice session on the weekend for an hour.
I've tried doing this for a couple of weeks and am having major problems with severe muscle soreness and headaches. Last night I started to experience distored vision in class and then had a killer headache all last night and then most of today. (I'm seeing a doctor on Monday about the distorted vision.)
I'm 38 years old, in pretty good shape, but about 20 pounds over my ideal weight. I eat a pretty balanced diet and get about 7 hours a sleep a night. I drink a lot of water during the day, but not during class (we get about one water break per 45 minutes in class). I don't drink alcohol often - perhaps one beer a week. I always warm up with some light combinations or forms practice and stretch at the end of class. I've tried soaking in a hot bath after class and that seems to help with the muscle soreness some.
Is there anything else I can do to reduce the amount of time my body appears to need between workouts?
