I was planning on lifting. (Specifically, I was going to do "Cindy," which is one of my favorites. Complete as many rounds in 20 minutes as you can of: 5 Pull-ups, 10 Push-ups, 15 Squats.)
But Scott called to say he didn't have to TA, so we met at the gym and climbed for an hour instead. Way more fun than lifting. Not quite as strenuous as a good Cindy, but I certainly feel it in my back today. Going to try to start climbing twice a week.
