Tips on exercise that I found in a nutrition class I'm taking

Getting started: Your physical activity program can be as simple as a
15-minute walk around the block each morning and evening. Gradually
build up your program and set new goals to stay motivated. The
important thing is to find something you enjoy, and do it safely. And
remember—trying too hard at first can lead to injury and cause you
to give up. If you have a chronic health problem or a family history of
heart disease at an early age, be sure to talk with your doctor before
launching a new physical activity program.
1. Set a schedule and try to keep it.
2. Get a friend or family member to join you. Motivate each other
to keep it up.
3. Cross-train. Alternate between different activities so you don’t
strain one part of your body day after day.
4. Set goals.
5. Reward yourself. At the end of each month that you stay on your
exercise program, reward yourself with something new—new
clothes, a compact disc, a new book—something that will help keep
you committed. But don't use food as a reward.
