This video helped me out .All the years I've been swimming I thought I was fairly well balanced but it seemed that my legs felt a little heavy at times with a mind of their own . Now my balance feels better and my 2 beat kick is easier. I was doing all the tricks for many years for finding balance such as keeping the head down, hand below elbow, leaning in to the water, ect. but I was not really finding perfect balance through my core to my legs. This video makes sense to me .For people who seem to find balance easy and can float well this may not apply as much.
