I'm hardcore, yo.
I went swimming tonight and 2 laps in my arm started hurting again like last Wednesday. It was a tiny bit sore on Thursday, but didn't hurt at all on Friday, Saturday, Sunday or today. There is something about a freestyle stroke that the muscle just isn't liking.
But I still did 90 laps. The further along I got, either it started hurting less, or the endorphins dulled the pain. I'm inclined to think it was all endorphins because when I got out and went into the locker room and wound down a little, suddenly it hurt to lift things with that arm. I'm not trying to hurt myself worse, but I'm in a swimming groove, and I can't lose it. After my shower I put some Tiger Balm* on the muscle, and that seems to be helping. Of course, now I smell like a medicine cabinet. Good thing my neighbor at work is on vacation this week.
So 90 laps, 32 in 14:10 (boo! I'm blaming my sore arm)
* The tiger growls on the website. Just a warning.
