The eggbeater kick is a hands-free form of treading water that allows the swimmer to remain vertical. It is a style of kicking where the swimmer's legs alternate one-legged breaststroke kicks. This form provides continuous support because there is no break in the kick.
The eggbeater kick allows the swimmer to freely use their hands, remain stable in the water without swaying, maintain a constant vertical position, and conserve energy. However, it can cause knee problems due to the circular rotation of the knee joint.
The eggbeater kick is used in several different types of swimming activities.
