To keep track, I do 3 sets of 15. My squats are now at 115 pounds and deadlifts at 65 pounds. The sore-for-several-days weights were 155 for squats and 75 for deadlifts. Next week, maybe I'll try 135 for squats, to see if that's sustainable.
Cardio tonight - I'm doing ten of the 30 seconds on/30 seconds off intervals, followed by however long I can keep going, which seems to be about an hour, total.
