Swimming is one of the best forms of exercise you can get. It works all the major muscle groups and puts minimal stress on your joints.
Swimming builds muscular strength, improves cardiovascular fitness, and improves your endurance. Humans have been swimming since the Stone Age. According to medicinenet.com, cave drawings showed people swimming. Even the Bible and Greek poems like “The Iliad” and “The Odyssey” talk about people swimming. In Egypt clay seals dating back to 4000 BC show four swimmers doing the crawl.
The Encyclopedia of Traditional British Rural Sports stated that knights were required to swim and the bathhouses in Rome were places to exercise. In this video, Rollo, a 6-month-old German Shepherd is learning to swim and fetch!
