[quote=Danny;63885]I think there are several objections that one can raise to Shaules' approach to posture. To me, the factor that he is missing is that freestyle requires core stability while rotating from one side to the other. It is not enough to simply keep your legs up while lying on your stomach. It turns out that the pelvic muscles are precisely the muscles needed to stabilize and transmit hip rotation to the shoulders, which is what powers the freestyle stroke.QUOTE]
If you watch the video again Shaules does mention about shifting your weight to the pelvis.
