P90X is awesome. You just have to be sure to stick with it. I wasn't the best at sticking with p90x because by the end of the day, I'd be so tired. But then I started using Advocare which has helped me sooooooo much. I have lots more energy and the Catalyst is like lipo in a bottle (ok not quite, but it does help a lot with toning). But when you use Advocare and work out, you get more muscle definition out of your workout. www.AdvoCare.com/110916315. I use the MNS 3 package and love it. Hope this helps!!!
