Hi, I have to say that I am somewhat confused about whether or not ,when I am doing freestyle ,if I should roll my body and rotate my hips.My Masters coach has said that the body should stay flat and that I should just roll my shoulders when I stroke and keep my hips flat.For me this means that my stroke length is shorter when I do this and also my time is slower.Can anyone please enlighten me.
