Hot tubs vs pools
People plug up there hot tubs or do something else.
Like a big battery or wires.
Swimming could be easy and hard, but fun.
Just try it.
A vital task in learning to swim is proper breathing. Swimmers inhale through the mouth. They exhale through either the mouth or nose or both. Coaches often instruct pupils to inhale deeply and quickly but to exhale more slowly. A swimmer can practice breathing by wading into water waist-deep, inhaling through the mouth and bending forward until the face is submerged. The swimmer then counts to ten while holding the breath, lifts the head and exhales. A swimmer can practice exhaling under water by keeping the eyes open and watching the bubbles. The swimmer then turns the face to one side and brings the mouth above the water to inhale.
A swimmer next learns to coast through the water. The swimmer wades into hip-deep water, faces the shore, and stoops down with arms extended beyond the head. The swimmer then shoves vigorously with the feet and floats as far as possible. In order to breathe, the swimmer pushes down with the hands, raises the head, and drops the feet to the bottom. A new swimmer should learn to coast 15 feet (4.5 meters) or so, exhaling under water. Swimmers who can do this are ready to learn the crawl, the fastest and most useful of all strokes.
When learning the crawl stroke, a swimmer floats on the stomach and kicks the legs slowly up and down from the hips. Toes should be turned inward (pigeon-toed) and the knees held straight but relaxed. To move more quickly through the water, the swimmer kicks the legs in a rapid threshing movement, or flutter kick.
