At 5'7", 170 lbs., 29 years old and lifetime natural, he says diet has been the key to developing and maintain a quality physique. "My diet consists of chicken, fish and occasionally red meat. It's also important to include vegetables with each meal to provide the body with micronutrients. I like to cycle my carbs to get leaner and stay full the same time. I use the '3 low, 1 high carbs day' method."
