Swimmer 5: Swimmers will be challenged with a whole new set of skills; shallow dives, tuck jumps (cannonball entries), eggbeater kick, and backward somersaults (in water). Technique and endurance will also receive greater focus as swimmers will need to complete longer distance swims of 50 m of front and back crawl, and interval training sessions for all their strokes. Swimmer 6: As the final level in the Swimmer program, swimmers will build up their advanced skill set. Swimmers will work towards mastering stride entries, compact jumps, and lifesaving kicks. They will also refine their strokes to increase their swimming strength, power, and endurance critical for success in the 300m workout required to complete the level.
