I haven't done the DVDs, but I did just start walking on my treadmill (due to the cold/ dark issue... plus I can do it during my son's naptime and don't need to hire a babysitter!). I've learned that after a few days of walking hard, increasing the incline and speed until I'm just barely not running... the more I do that, the more willing I am to just try running for a minute at a time. Then 2 then 5! My personal goal is to just get my heart rate up for at least 45 minutes a day, and I know that in the past, I've definitely been successful losing weight with this walk/ walk-jog regiment. Hope this helps!
