Drove to Santa Cruz and picked up a very nice bench for $40. Aside from finding a better way to do chin-ups (although my bag stand isn't too bad) and replacing my barbell I'm pretty much all set with the equipment side of things.

Woke up yesterday with my back much worse. Very debilitating. Today it's better and I was able to do a Tabata circuit of calisthenics and low-weight squats. I basically switched from 50 lb goblet squats, decline push-ups, and chin-ups, done 5 reps each over 10 minutes. I definitely underestimated myself. Even though I was breathing plenty hard the time seemed to speed by and I had a lot left in the tank. Will go for 15 next time. I wasn't exactly rushing to the set-up of each exercise, though, because of my back.
