A week ago I had a conversation with a friend, and be both concluded that we would like to exercise more. Well, I had just purchased a new workout video and I invited her over to try it out with me. In general, I choose to purchase workout DVDs instead of going to classes because then I can look foolish in the privacy of my own home. Also, I can pause the video when I need to take a break. :P
We both admitted to one another that had we been alone we would have turned the DVD off a long time ago. So not only is it good to have company while doing knee rolls, it's also insurance against quitting midway.
Word to the wise, if you're going to do jumping jacks and fake jumping rope you'd better choose a good friend to do it with.
