BUTTERFLY
In the 1960s, I used to swim butterfly with a pronounced key-hole arm action which gave me time to fit in a second minor dolphin kick. My legs used to separate on my second dolphin kick. As a Masters swimmer in the 1980s, I started to swim butterfly with a single dolphin kick pulling straight through without a key-hole arm action. A number of Masters swimmers use what I call gallomping butterfly where they pause with their arms in front to enable a strong second dolphin kick. This style of butterfly is less strenuous, which suits some Masters swimmers who have lost strength with age. At the age of 76, I am not yet prepared to adopt this style of butterfly.
