Swimming is one of my favorite ways to exercise and I feel like I can think so clearly under the water.  It is no wonder that swimming is always one of the top rated activities!
I would love to swim for exercise! I just kind of flutter around in the water. Is there a certain stroke I should learn?
If you are afraid of having your head under water I highly recommend the breaststroke because you can keep your head up and go slow with no problem.  The backstroke is a nice relaxing stroke.
