Teen raising hand in classIf you're like a lot of teenagers, you may think that exercise means playing sports. So if you're not very good at sports, you might not be motivated to try any kind of exercise.

But exercise is simply about moving your body -- which can be almost anything that gets you active, like walking, throwing a Frisbee, or vacuuming your room. It doesn't even have to involve competition.

If you're not being active, you are cheating yourself from all the benefits exercise can bring you. Like did you know that teens who are more active may do better on tests?

Yep, exercise not only builds your fitness, it also boosts your brain power, which can help you do better in school and improve your grades. Studies show that teens who do aerobic exercise -- like walking and swimming -- have bigger brains. In particular, exercise enlarges your brain's basal ganglia (the part that helps you pay attention), even through another ho-hum chemistry class. One school has shown that 30 minutes of walking on a treadmill improved students' problem-solving skills by 10%. That could bump you up a letter grade!

Being active has other benefits too: It can also help you sleep better, feel more energetic, and be less stressed.

Feeling motivated to give exercise a try? Here are a few simple steps you can take to get on your way to building your brain power through fitness.

Start With a Small Goal

So you can't run a mile right now. No sweat. You don't even have to make running your goal. Studies show that just 20 minutes of walking before a test improved students' scores -- whether or not they were fit when they started.

Start exercise slowly, and go with what you know. If you can walk for 10 minutes, begin by going for a 10-minute walk every day. If you can walk longer than that, great. Go for it!  Just remember it is OK to start small.

Be truthful with yourself about what you can do without stress. Setting a short-term goal that's easy to measure will keep you motivated to do it. With each success, you'll be building your confidence, too.
