Perhaps you have a physical disability. Or maybe you have a chronic condition that limits your mobility. You're adjusting to your disability — but your doctor recommends you get more active.

Take the recommendation to heart. Exercise can help you manage your weight, maintain your independence and improve your quality of life. Here's help exploring your options.

Check with your doctor before you begin to exercise. Once you have your doctor's OK, start slowly. Begin with gentle activities, such as stretching. Gradually increase the length and intensity of your workouts. Stop exercising if you experience pain, discomfort, nausea, dizziness or shortness of breath.

Walking through your neighborhood or wheeling yourself in your wheelchair counts as exercise. But you have plenty of other options, too. For many activities, minor modifications — such as slowing down the pace, using modified equipment or playing in a wheelchair — are all that's needed.

Strength training can make it easier to complete everyday tasks, which can help you maintain your independence. If you have trouble using your hands, consider wrist cuffs that secure free weights to your hands. If you have involuntary movements of your arms or legs, you may want to use strength training machines for enhanced stability when you exercise. Many cable-based strength training machines can be used from a wheelchair.

You can even build muscle strength without special equipment. Soup cans, water bottles, resistance tubing or your own body weight may work just as well as free weights or strength training machines.

If you have a condition that directly affects your muscles — such as cerebral palsy, muscular dystrophy or multiple sclerosis — your doctor may recommend specific strength training exercises or modifications to your technique.

If you can't ride a traditional bicycle because of paralysis or amputation, try handcycling. Handcycles have three wheels. You pedal and steer the handcycle using only your upper body. With a recumbent handcycle, your torso reclines and your legs are out in front of you. With an upright handcycle, you sit just as you would in a wheelchair. As with any type of bicycle, remember to wear a helmet when you ride.

If you need to go easy on your joints, try swimming or water aerobics. If you're feeling adventurous, check into a custom-made canoe or raft seat with padding to protect the buttocks and legs. Riding behind a boat on a specially designed wakeboard may be another option. You sit on a special seat mounted to the wakeboard, and side skis help keep you upright on the water.

If you prefer winter sports, consider skiing. If you have one leg, downhill skiing may be possible with three tracking — one downhill ski and two outriggers for balance. The outriggers are adapted forearm crutches with ski tips mounted on the bottom.

A monoski or biski may work, too. A monoski has a molded seat attached to a single ski. You use hand-held outriggers for balance. A biski consists of a rigid seat mounted to two shorter, wider skis. Outriggers add even greater stability.

Another option may be a cross-country sit ski. Sitting in a molded seat, you push yourself along the trail using ski poles with tips that dig into the snow.

Beyond the basics, keep an open mind. Maybe you could play volleyball with a larger, softer ball or in a seated position with a lower net. Tennis can be played from a wheelchair. Golf, too. Try a modified club, gripping aid or teeing device. You can use larger balls or shorten the distance to the hole as well. Yoga poses can be adjusted to meet your needs. You might find local wheelchair teams for soccer, basketball, floor hockey, bowling or other sports.

Whether you go it alone or team up with friends, loved ones or others with disabilities, enjoy yourself when you exercise. The reward? Better health and an improved quality of life.
