Exercise. Get fit. Watch your weight. We see these messages all around us in magazines and newspapers, but how do you choose the right activity?
There are three main goals for fitness. First, strengthening the heart and lungs. Second, strengthening the muscles. Third, controlling body weight. Not all activities will meet each goal. You may center on one goal or, for total fitness, all three.
Running
No other exercise will help you lose weight faster than running. It also strengthens your heart, lungs, and leg muscles. But it can hurt your joints. If you feel pain in your knees, you need to stop and choose a different activity.
Walking
This activity puts less stress on the body than running. But to see results you need to get your heart beating faster. This means you’ll need to walk fast.
Swimming
Swimming is a great way to strengthen different pasts of your body. But if weight loss is your goal, you may want to pass on the pool. The water in a swimming pool is cooler than our body temperature. The body naturally protects itself from the cold by keeping fat.

We often hear of elderly people falling and hurting themselves. They just don’t have the strength to catch themselves. Lifting weights can prevent that. It also helps prevent injury form other activities. The drawback to weight lifting is that you’ll need to pay for a membership at a gym.
