Well, it looks like I'm on a strength training break (at least, anything but lower body) until I figure out what the heck I did to my chest. At first I thought it was just pain from doing ab work, but it hurts to even lightly touch my sternum or bottom ribs, so that's definitely related to the bones and not the muscles. Sitting up from a lying position is extremely painful, too. I think I must have bruised it while working on the toilet yesterday. It's a cramped little spot, and I was bending over the bowl a lot to reach the nuts and bolts so I could remove the tank and replace some parts. So, all I can really do is lower body work in the meantime. This sucks.
