I want to start off by saying thanks to those who take the time to answer beginners questions. Reading through these forums has changed my body completely. I am 17 years old and weighed 180 lbs at 5 10" now I weigh 140. This is all because of following a diet and working out 5 times a week. I feel better about myself now and have alot more energy. For all you people just starting a work out plan read through this site and I promise you will find all the answers to your questions.
