LWAYS was one of those kids who could eat whatever they wanted, drink whatever they wanted, and not gain a pound. Rather always had a very decent physique/flat stomach. They said it wouldnt last, and it didn't. Started college at 148-150, now im 165, and its actually noticeable, which I don't like. Quite literally gained the freshmen 15 I used to be on the swim and wrestling teams in HS, so that definitely helped me stay in shape. Nowadays I dont even go to the gym, but facilities are available. I'm knowledgeable for what to do in weight training, it's the cardio that i'm unsure about. Treadmills Elliptical Stationary bike...? What are good cardio excercies to lose weight?
