Swimming is a good exercise option for people of all ages and fitness levels—even those with disabilities or chronic pain. When you’re in the water, your bones and joints don’t bear all your weight. The vigorous movement of swimming places stress not on your weight-bearing joints but on your muscles.
Strength
While swimming is low impact, it’s still a great way to get strong because swimmers use major muscle groups in both the upper and lower body. And water offers 12 times more resistance than air, forcing swimmers’ muscles to work harder.
Endurance
Muscular strength alone is not the same as overall fitness. Water exercise, though, can build both strength and cardiovascular endurance. Swimming develops muscle strength through water resistance and raises cardiovascular endurance through aerobic activity.
Flexibility
Swimming, in tandem with good stretching, can boost flexibility and range of motion. Water’s buoyancy, resistance and temperature encourage muscle flexibility, and the smooth movements of swimming tend to stretch and lengthen muscles.
Weight management
Regular, calorie-burning exercise is key to successful weight management. People weighing 150 pounds can burn about 400 to 700 calories per hour while swimming, depending on their activity level. Frequent, regular swimming can speed metabolism, lower body fat and improve the body’s ability to burn fat.
Cardiovascular health
Because swimming uses so many muscles and your body is working against water resistance, even a low-key water workout can elevate your heart rate. When you’re swimming, your heart, lungs and circulatory system go all out to deliver oxygen and energy to each of your moving parts.
Overall toning
Olympic swimmers have terrific physiques. Years of training in the water have given them long, lean bodies with toned muscles. Swimming is the perfect sport for anyone who wants to feel fit and healthy—and look it.
