Age: 18+ Adult swimmers will practice different entries into deep water including dives, rolls, and tuck jumps (cannonballs). As they work on building strength and endurance, they will aim to be able to tread water for 1-2 minutes. New underwater skills are introduced such as handstands in shallow water and front somersaults (in water). Swimmers will achieve the Swim to Survive standard by being able to roll into deep water, tread water for 1 minute, and swim 50m. In addition to improving their front crawl, back crawl, and whip kick, swimmers will be introduced to breaststroke.
