Heather, I am a Beachbody Coach and I can help! I haven't done P90X, but I have done several of their other workouts, Insanity, Insanity: Asylum, P90X2 and 10-minute Trainer. Have you looked into Beachbody's health meal replacement shake, Shakeology? I have been drinking it for a LONG time now and can imagine starting my day without it. It increases energy, helps you lose weight, regulates digestion and can even lower cholesterol.
Go to www.myshakeology.com/RKM1302. You can read all about it and even watch videos of people who have had amazing success stories from Shakeology. I was very skeptical at first until I tried it myself and saw the results. After my first round of Insanity with Shakeology, I lost 15 pounds and was in better shape than I ever was while on active duty in the Marine Corps.
