Thursday: Relatively quick work-outy-thing at home since (a) I have a lot of other stuff to do, and (b) I kinda screwed up my food schedule, so I didn't have enough energy to push very hard. :/
I hate upper-body work. Hate hate hate.
Did like 40 ... sit-ups? crunches? whatever sit-ups are called when you don't have anything underneath your back at the bottom. Those were interspersed with 60 of a pushup-like motion against a wall (with the angle sufficiently unfavorable so as to force my muscles to do at least some work). High-energy dancing (probably at the level of jogging) at the beginning and end.
The whole thing probably lasted less than a half-hour. Arms are definitely tired, and I never can tell with my abs until the next day.
Also: I started to get a mild headache (which, I've learned, is my body's way of saying "STOP before you get fucked up"). It's food time.
