Breaststroke: Arms move simultaneously under the water horizontally, with legs doing a frog kick
Do you experience any pain with kicking during your swims, particularly with a frog kick?
One of the Cavills supposedly describes it as "crawling through water." Hence the name "Australian crawl," which today is more commonly known as "freestyle." Until that point, the fastest stroke had been the "trudgen," which combined the overhand motion with the existing frog kick associated with the breast stroke.
