In freestyle minimal sound should be heard. Sound is a form of energy and energy is wasted if the swimmer smacks the water! Often times these swimmers appear sun burnt, but their forearms are red due to water abuse, not UV rays. This high drag stroke is a confused form of straight-arm recovery and does not enhance swimming speed. Instruct the swimmer to have their hand enter first, followed by the rest of their arm. Having the whole arm enter through one hole will decrease drag and increase speed, yay!
