Long Bow

Don’t slouch. Take that navel and throw a hook in it, pulling you forward with a chin parallel to the ground. The curvature of the spine allows the hips to be capitalized acting as the hub of lower and upper body. If you lax on this, not capitalizing on your backbone, then the center of gravity changes either resulting in a shortened stride for the same effort or too great of a displacement of the body aka staying in the air too long. Remember the bow is what you want, it allows you to go strong longer.
