Hello, I play football in highschool, and have been playing football for 5 years now. My problem is, even though ive been working out for 5 years, I am extremelly out of shape. I have increased my stamina ever so slightlly over these years. I am barelley over wieght, yet I still am in the back, running with the 300 pound guys. I am even active outside of football practice, playing football with my freinds, and walking around my block often. This is starting to really frustrate me, to the point were I over work myself and nearlly pass-out. Is there a possibility that I cant get any more stanima than I currentlly do? The onlly thing I can see that could get in my way are video-games. When I was a really little kid, I would sit and play video-games all day! Now I only play video-games like 3 times a week, and only for a hour or so. Is there an effect that video-games can have you, to thwart my progress as an athlete?
