As "boring" as Leslie can be, I did part of one of her one-mile walks (the series with the weighted balls that the backgrounders seem to find unintentionally hilarious
) as an add-on to the FIRM Powersculpting workout that's only 20 minutes long. (I have a pathological need for all workouts to be at least 30 minutes, haha). Doing just ten minutes of a one-mile was perfect, got me to my 30-minute mark, and it was gentle enough that I wasn't exhausted. I even left the sound on, which I don't normally do. Nice motivation, easy moves, comforting, gets my heart rate up just enough to act as a warm-up or cool-down to something else, and if I run some of the segments, it's even better. Leslie is perfect for when you can't get outside or just don't have time, and her stuff is very easy to modify up or down.
