No one swims freestyle this way.
Now I still find the movments exagerated, but they do show the principal of the strange movements a lot of fast guys make.
It doesnt look so weird anymore, but if I trie his dryland routine in front of the mirror, my shoulders cry out loud and it looks pathetic, although better than before.
Can anyone be comfortable copying this guy?
(i know it is not needed to do so to swim pretty well, just curious how others compare)
Not a comfortable position. Or is it for you?
