Jiujitsu Revisited

going back to training Jiujitsu after a break of 2 years has taught me a few things. One, sitting in a chair is terrible for intercostal muscles. I trained with this older Japanese dude at the recreation center here in san francisco, along with two other kind hearted souls. The dude is ~61 years old, but a meaty 5'5", and when he had me in side control, and I was instructed to escape, I used intercostal muscles and strained cartilage that typically isn't strained on my body. In fact, the last time I strained it, was when I was taking Gracie BJJ in Long Beach, when a fellow of about 190 lbs, was trying to pass my guard while based on his feet. It doesn't feel as bad as the first time I aggravated the tissue, but there is still something definitely wrong with the area. I'll probably increase the ibuprofen, but now that I'm eating 1 meal a day, I don't really don't think it's very smart to exercise anymore than I already am. Anyway, all this having been said, I realized sitting in a chair, after noticing the slouching affect that occurs by depending on the back of the chair to provide back support, is terrible for intercostal muscle. chair without a back, now that would be something...in fact, I should probably move my notebook now, so that I can sit on the floor...I have to practice Jhana anyway...
