The photo above is of the goggles I use in martial arts class--gc from nz was asking to see what I use.
The lenses are prescription, allowing me to see what's going on around me--I'm blind as a bat. They also stay on my head, which is an issue even in core class when there's no contact between students.
And importantly, they protect my eyes. My eye doctor is not keen on my doing martial arts--my eyes are so myopic that I'm at high risk for a detached retina. Getting hit in the head is bad enough, and getting hit in the eye would be really bad. So this offers me some protection from a detached retina.
I had another two satisfying classes. On Thursday, I was tired at the end of the day and hot a happy camper from work. When I walked into class, one friend asked me, "Who are YOU mad at?" By the end of class, I was, well, a happy camper. Martial arts has a great anti-depressant effect on me.
My knee hurt a little bit from having torqued it, not in a kick, but in a defensive move--we worked on defending ourselves from a one-armed choke from behind. It wasn't awful pain, just enough to remind me to still be careful.
I attended another class last night because I was going to miss my Saturday class due to a family trip.
I really like my new sensei. He's very focused and a great instructor, and he makes an effort to individualize his instruction, even in a big class. I got a DVD set of his amateur and professional competitions--just basically home-made videos, nothing fancy. He points out in the cover notes that even though he teaches people to master technique, then speed, THEN power, in his early matches his technique is poor! And it improves. For one thing, his punches were kind of like haymakers in the beginning, and then they get more straight.
I know when I was active in kickboxing before my torn ACL, I'd work, work, work on some subtle move in class. Then sparring would begin, and I would drop everything I learned and just try to survive. And it's much more primal in competition than sparring class.
