One of the biggest challenges I've had this year is exercising more. I'm getting better at eating healthy, but I've been working on exercising more. But I've never been good at exercising. Recently, I bought my first exercise DVDs. The first one I'm trying, Jillian Michaels' 30 Day Shred, is meant to be a quick, intense workout that you do every day for 30 days. The advertising says you can lose up to 20 pounds in 30 days. I figured it was worth a try. And I'm glad I did. I learned some pretty important lessons.
