How can I improve my dolphin kick? I feel that my dolphin kick is weak as anything, and I am having trouble with the nice undulating motion of dolphin kick. I am told that the body should undulate from the armpits all the way down with the hands streamlining and staying quite still. Yet my undulating motion feels unnatural. What are some drills or swims that I can do to improve it? And any other tips anyone can give me about dolphin kicks (the backstroke start dolphin kicks too)? Thanks a lot.
