Swimmers learn to jump and float in deep water, diving from the sitting and kneeling positions, treading water in deep water, and the mastery of rotary breathing. Swimmers continue to work on their front crawl and elementary backstroke sills they learned in level 2. They will also learn how to do these kicks: whip kick, sidestroke kick, and dolphin kick. Your child should be comfortable in deep water and be able to swim across the short end of the pool without a lifejacket or a noodle to sign up for this class.
