Physical Fitness and Health
Physical fitness is a balance of several things. It is best if you work on all aspects of being physically fit including: cardiorespiratory (aerobic) endurance to help the heart, lungs, and circulation by increasing the heart rate during exercise; body composition to decrease amount of body fat; muscle strength and endurance to help muscles work well without fatigue; and flexibility to improve ability to move and stretch the muscles and help prevent injury.
Make a commitment to be active every day. Consider a physical education class, a community team sport, or developing your own exercise routine to fit your schedule and lifestyle. Ask a friend or family member to join you. You must like the activity you choose.
Make a commitment to stick to your routine at least 3 months before reevaluating whether you want to continue. This gives you the opportunity for the routine to become a habit, making it easier to stay with it.
Many daily tasks can be made more effective in keeping you physically fit also. Use the stairs instead of the elevator; park at the far end of the parking lot and walk; do stretching exercises at your desk; gardening, housecleaning, or play a game of catch with your child instead of watching a TV show.
Everyone needs some physical activity, regardless of your health status. The type and extent of the activity you choose must be geared to your current condition. Too much, too soon can be both harmful and discouraging. If you have a heart condition, injury, disability, chronic disease, are in poor physical shape, if you are significantly overweight, or if you are over 40, it is especially important to talk with your doctor before beginning a new exercise program (Krames).
