I am a 45 year old woman, am a single parent of one teen and a not quite yet a teen, i work full time, and will be going back to university soon, one night per week.........sometimes i am into my weight loss and exercising, sometimes i am not. i started being into it again, trying weight watchers this time and will soon be on P90X, hopefully i will stick to it this time. I lost 40+ pounds 4 years ago, gained 50 pounds again, i have been a yoyo for several years.
