When it comes to fitness, give yourself something to work toward. Start with simple goals and then progress to longer range goals. Remember to make your goals realistic and achievable. It's easy to get frustrated and give up if your goals are too ambitious. If you haven't exercised in a while, a short-term goal might be to walk five minutes once or twice a day. An intermediate goal might be to walk 20 minutes three or four times a week. A long-term goal might be to complete a 5K walk.
