(no subject)

Note to self: take the ab crunch machine slower next time, especially any parts where I get to a point that requires me to pause and catch my breath. I spent several hours yesterday wondering whether the small dull pain in my back was an incipient kidney stone or a muscle injury from the ab machine. Since I did not wake up last night in pain and puking, and I'm awake and all right today, I'm gonna go with the machine- but still.

Will be more careful today, of course. Today is pushups and stairs.
