Later, I'm on the adductor machine (the one where you bring your knees together against resistance, or as I call them the "squeezies"), and I'm doing the first part fast to build explosive strength because I want to get back to playin volleyball in the spring.
And something goes "ping". Or, rather "grounch". I get out of the machine and realize that I strained a groin muscle, and it's bad enough that I can't lift any more.
I'm not incapacitated, but definitely sore. The Advil and red wine haven't completely taken the edge off. I'm limping around a bit and it will take a couple days to recover.
Moral of the story: Listen to your body when it says "You know, Yeff, maybe today should be an easy day." Your body knows best.
