One of the things that I have said over and over again, has been the value of the TEAM concept when it came to losing weight. I am convinced that there is absolutely NO other way that I would have been able to make it. The people that I worked out with- still work out with, keep me accountable and keep me focused by providing an element of competition. At the same time, I like to see my team mates do well too.
I have seen this time and time again- just think about Weight Watchers. The people that succeed come to the meetings and have contact with others that share the same experiences.
