Another vote for Jillian and the 30 Day Shred. If you actually do it every day for 30 days...wow at the difference. Really, it was amazing for me. I also love her yoga video, but just be prepared that it's not "true" yoga. Awesome results, though. I also took up running. I didn't do C25K, but I know it's awesome. I just got confused too easily with that. I just went slowly and worked up and was able to run a 5K in about a month or so. Now I run several times a week.
I'm still not where I want to be, but using these tools has really helped me feel better about myself.
