m feeling particularly energetic (not often), I like to do
yoga or the Leslie Sansone videos. I have DVDs (I'm older than you... lol), but you can find both on YouTube, as well. Leslie Sansone has a beginner walk that equates to ~ a mile walk that's kind of fun. I do that every once in a while. https://www.youtube.com/watch?v=ECxnTuzZ614 This is an older one, but she has some new ones, as well, plus some that are much longer and more strenuous.
