Why us it when i run or work out for 10 minutes i feel dead tired?

You could be getting dehydrated or muscle fatigue. It could also be a matter of not being in good shape. Make sure you drink plenty of water before, during, and after your workouts and running. Improve your cardio capabilities by walking and then building up to power walking, jogging, and then running when your body can handle it better. It takes hard work but you'll get there!
