How can you improve your endurance when exercising?

Exercise: Begin your exercise program slowly with lower weights and lesser times. As you get stronger, you should be able to do increasingly more weight and times. Give your muscles time to accomodate the changes so that you don't pay the price of overexertion. Listen to your body. It will tell you when you can do more.

Increase distance: Increase you distance by no more than 10 percent each week.
