The Perfect Excersice is Swimming?

These about the benefit of swimming.

If you're too shy to lift weights gym, suffer from injuries or joint problems that make it hard running, or are simply looking for an exercise you can do regularly, you will have fun as you draw health benefits, consider swimming. Swimming is the perfect exercise: it burns calories, strengthens the cardiovascular system, helps build and tone muscles and by people of all ages, abilities and states of health can be assessed.

Swimming is beneficial for people who suffer from a variety of painful physical conditions or disabilities, such as arthritis, rheumatoid arthritis, and knee or back problems, as well as for athletes recovering from injuries. Swimming puts little impact on the body's joints since nearly 90 percent of your body weight is supported by the water when you are immersed. Dieters can benefit because 30 minutes of swimming burns between 260 and 400 calories. Swimming can also help relieve stress and anxiety.

Swimming is an aerobic exercise. It uses large muscle groups, and if you swim for a minimum of 15 minutes, your heart rate stays between 60 to 80 percent of your maximum heart rate -- this boosts your cardiovascular system by conditioning the heart to deliver oxygen to your body's tissues in larger amounts and more quickly.

Swimming provides an overall workout for the body's major muscle systems, and can effectively define and tone the legs, upper arms and shoulders. The Disabled World website reports that because water is significantly denser than air, your muscles must work approximately 30 percent harder when you are swimming than they do in land-based exercise. This extra muscular output can help burn fat, increase endurance and build lean muscle tissue.
