POOL TO OPEN WATER
In life, “treading water” is a euphemism for failing to make progress but for swimming outside, it’s a useful skill to master. It allows you to wait for your friends and lifts your head out of the water so you can take in your surroundings or adjust your goggles. If you can learn to tread water without using your hands, you’ll free them up for waving to your friends or taking pictures.
