Dear Muscles,

Ohhh . . . you're angry with me today!  Yes, I spent time with the treadmill yesterday (some free weights, too).  Let's agree to stick with it for a few days and you'll get used to my renewed friendship with the treadmill.  Now you're hurting, but it'll get better.  It's a good thing.  I promise!!  I need you, muscles!  Can we be friends again?

Sorry I hurt you,
Kristi
