I signed up for Master's swim classes at my club, and have been going for the last 4 Tuesday's at 6:30PM. There are about 12 of us in the class, and a third of us are focused on endurance (long-distance) swimming for Triathlon. Actually one of the guys wants to do really long distance swimming - a later post on that (he recently did 10 miles).
My challenge is to add kicking to my swim, which I started with this class - beforehand I've done all my swimming with my arms. So I am kicking now, but not correctly. My coach has suggested several improvements, but I can't see what I am doing now with the advice.
Today at lunch, NBBW and I were discussing a way to drag some kind of device behind you while you swim with an embedded iPhone so you could film your kicking pattern. One idea was a strap around your waist, with a cord hanging behind you dragging a floatable device that would be holding your iPhone in a vertical position underwater (in a clear plastic bag) pointed towards your legs and able to capture your kicking movement. More to come on this...
