Q&A for How to Train Your Body

Consider joining a gym. Many memberships are as low as $10 a month. Gyms offer you the ability to do most exercises inside. You can do a variety of cardio, strength training and even take classes. Even if you may not need the equipment at the gym, it might be nice to have the option to workout inside if it's a rainy or cold day.

If you're brand new to running and you want to get in the habit, just start out by going for a 10 to 15 minutes run every day. Once you're comfortable with that and you've got the form down, you can start working your way up.

But if you are nine years old, you probably don't need to worry too much about getting into shape.

Working out when you're younger is great, but both men and women should hold off on heavy weight lifting until their later teen years at the earliest.

Depending on which body part you are trying to isolate, these can include bicep curls, calf raises, leg extensions, hamstring curls, lateral pull downs, rows, skull crushers, shoulder presses, etc.

Start with 5-10 pound weights, then work your way up to 15-20 pounds when the other ones become too easy.
