My back is coming along. It still spasms when I stand up if I sit for more than an hour at a time, and I am very conscious of my posture these days. However, I am going to do some light training tonight (push-ups, pull-ups, chest supported rows, maybe some cardio stuff) hopefully Saturday, or maybe Monday I'll be able to participate at jiu-jitsu class (prolly no sparring, but at least do technique). Last night I went to class. I didn't train (obviously) but did go to see the folks, and watch the techniques of the day. Last night's was a cool transition from guard, to take the back, to choke, to arm-bar. I'll have to try it once I get right.
I hope you're vaguely rockin.
