What could cause me to have such little stamina when i've been doing so much cardio training?

I've been on the wrestling team for the past couple of months. Although i ussually don't do cardio i've have been forced to do serious cardio training. But i still have crappy stamina. I am fourteen years old, i eat lots of fast food, and i am african american

You said the magic words: FAST FOOD. There's a lot of fat and grease in fast food, which your body has difficulty processing. So, your body steals energy to digest food when you need it elsewhere.





Most people find themselves weak when a workout comes up because they don't have enough blood sugar or protein in their system. Also, be sure your hydration is up.





Before I work out, I make sure I have 2 bottles of water in the 2 hours leading up to it (assuming you're in class or otherwise inactive). Try to have protein an hour before the workout (I prefer a yogurt or hard boiled egg because they're quick to eat). Just before you go to change, have some fruit (a banana, orange or something) to get the glucose into your system. This should give you sufficient short-term and long-term fuel for a good workout.
Reply:There is a difference between long distance training, and short bursts of intensity. Wrestling is quicker and harder. Try jump roping
Reply:stop eating all that fast food. Have you ever watched the movie called supersize me? Change your diet and that will help a little. cardio does make you tired. Try weight training too.
Reply:You might have low potassium. You need to eat healthier. Just because you have youth on your side doesn't mean that you can eat haphazard. Eat right, take vitamins and get some energy. You should also get a check-up.
