Whole body workout while swimming

Above the health benefit of swimming.

The  benefit of swimming is that it is a whole body workout. Indeed, to swim for any sizable amount of time, you need to engage all the limbs or you risk to be quickly exhausted. As a consequence, all the muscles in your body are mobilized for locomotion.

You will get an even better workout if you swim several swim strokes because you will mobilize the muscles in several different ways.

Finally, as swimming engages all limbs in different kinds of motions, it promotes flexibility of the joints.
