"Swimming improves heart and lung efficiency, enhances muscle strength and endurance, improves flexibility, and reduces stress. It's easy on the joints, and uses more muscles than most other forms of exercise. Although swimming burns a great deal of calories, recreational swimmers tend to lose less weight than would be expected from other types of aerobic activity. Scientists say that cold water removes heat from the body, stimulating appetite to keep the body warm. Exposure to cold water may encourage the body to maintain fat stores for insulation. To lose weight by swimming, it’s necessary to cut down on the calories you eat, and to swim fast enough and long enough.
Swimming can burn more than 660 calories an hour when performed correctly and causes fewer injuries to joints and muscles than aerobics or jogging. It takes only three hours a week of strenuous swimming to improve flexibility, increase strength and build cardiovascular endurance. Swimming provides a good aerobic workout if 25% of the total laps are performed at maximum intensity. However, only 5% of those who swim do so at an aerobic pace.

hi Gabriel
Swimming makes me very toned, tightens everything up but does tend to build my legs.
i tend to combine it with running for more fat burning...
not a scientific answer, just a personal experience.
