Since the human body is only slightly less dense than water, water supports the weight of the body during swimming. To be more hydrodynamic, swimmers can either increase the power of their strokes or reduce water resistance, though power must increase by a factor of three to achieve the same effect as reducing resistance. Efficient swimming by reducing water resistance involves a horizontal water position, rolling the body to reduce the breadth of the body in the water, and extending the arms as far as possible to reduce wave resistance. Because infants are innately able to swim, classes for babies of about 6 months old are offered in many locations.
This helps build muscle memory and makes strong swimmers from a young age.
