I'm confused as to where my head position should be. I understand that it should be aligned with the spine, but that's all I get. On the DVD Freestyle Made Easy, the woman that wears the fist gloves has her head inches below the water, while one of the guys has his head just peaking out.
A swim coach told me I look like a submarine because my head is so far under the water. She said my head should be peaking out of the water to help be more hydrodynamic, that if my head doesn't break the water for the rest of my body, my shoulders will and that will create more drag.
How important is head position? Should I be more concerned about correct body position and whether or not I'm a sinker than I should be concerned about head position?
