Neef some insight on relaxing and shaping the vessel
I am a bit confused: TI focusses a lot on the concept of relaxing and turning of muscles that are not necessary. On the other side the body needs tot be streamlined and as straight as a surfing board.
How to understand this correctly?
Elements of shaping the vessel: to keep it straight in my view, you need to push your upper body down, tighten the stomic muscles, push your bottom up and keep the legs aligned. All of this to me seems pretty 'active', muscles driven: relaxing here is equal to a spaghetti going through the water.
Elements of relaxing: the ragdoll arms of recovery, other? Maybe the fact of breathing, then the turning your head down and wait wait till the arm hits the water to drive the hip and dive into the tunnel: is this also 'relaxation'?
Insight on the difference of both concept please
