Hi there. I have the P90X series and watched friends find great success with it. I, myself, am a weightloss success story; having lost almost 100 pounds and kept it off for the past 3 years...however, the last 20 pounds has been a tremendous struggle and I've been stuck at this weight for a long time. Well, I've got a landmark birthday in March and want to ROCK it! So, I'm in and dedicated to this challenge!
