"pain is weakness leaving the body"

Apparently, a lot of weakness is leaving my abs and calves today... Pain is good. It means I'm working the muscles, it means they're getting stronger. 20 minute walk with dh and then a 1-2 minute jog later (reeeeaaaallly out of shape. I'm working my way up to it.). I consumed less than 1200 calories today. I'm not ready to start singing "I'm sexy and I know it"- I'm about a year away from that, but I'm feeling pretty good about my progress! Go me!!
