Swimming is one of the best activities that you can perform for overall physical fitness. First, swimming involves almost all of your major muscle groups. For example, the standard crawl stroke uses the neck, shoulder, chest, back, triceps, and biceps muscles of the upper body, the abdominal, low back, and oblique muscles of the midsection, and the gluteal, quadriceps, hamstrings, and calf muscles of the legs.
Second, swimming is an excellent exercise for conditioning your cardiovascular system. Although you won't go as far in a 20-minute swim as you will during 20 minutes of walking, running, or cycling, the cardiovascular benefits are essentially the same.
Third, swimming seems to enhance joint flexibility, especially in the neck, shoulders, hips, and midsection area. Much of this is due to the repetitive twisting movements as your body turns from side to side during the crawl stroke.
