FAQ
Frequently Asked Questions
In modern swimming terminology, they are generally synonyms for the breaststroke leg action. Some purists argue 'whip kick' emphasises the final snap of the ankles, but they refer to the same technique.
No, not legally in competition. A frog kick while on your back would be a violation of backstroke rules, which require a continuous alternating or simultaneous flutter/dolphin kick. It is sometimes used in survival swimming or underwater hockey.
It is named for its direct visual resemblance to the swimming motion of a frog's hind legs, which pull in and then push back in a rounded, powerful movement.
It is powerful for propulsion but also creates significant drag. The dolphin kick is often considered more powerful for underwater speed, but the frog kick is uniquely suited to the rhythm and rules of the breaststroke.
