Does swimming has benefits?

Hi! Steemians...wish you have a blastful day today!!!
This is my son Marc. He loves swimming. I believe this is his stress reliever.
Two years ago, my husband enrolled him in a swimming lesson at Indiana University, Lapu-lapu City. The schooling period was about two weeks. I had this question in mind, does my son learn to swim for this short period of time? The lesson started the basic technique like bubbling ang paddling. As the days went on and the training ended,my son knew how to swim and enjoy much.
Does swimming has benefits?
Swimming is a good all-round activity because it: keeps your heart rate up but takes some of the stress off your body, builds endurance, muscle strength and cardiovascular fitness. Helps maintain a healthy weight, healthy heart and lungs.
