Underwater dolphin kick

I noticed that Natalie Coughlin kicks underwater dolphin kick on her side for the 100m fly SCM recently. I have always felt it was easier to kick on your side or kick on your back. Why it is easier than face down, I don't know. Perhaps it is physics...... perhaps it's just my own inability. I didn't know it was legal to kick all the way on your side on fly. This sport has changed too much. There's too much "cheatin" going on now. I can't handle it..... :-) John Smith

    SDK on my back is by far the best technique I have. I think that it's to do with the head and gravity assisting the downward movement of the head (when on your back). You engage your abs to raise your head. When on your front you have to use the back muscles to lift the weight of the head. With my back issues this could be just something that I have found, but I think the abs and the body bend forward (contracting abs) easier than hyperextending--in a normally fit person. Do all work mindfully on the weak points. You have no excuse if even I SDK front, back, and sides! ;)
