This is probably the most shared statement I've ever made on #facebook which really is simply an extension of the thought process I've learned from FP founder Naudi. Thank you for the detailed elaboration @functionalpatternsnina and @jack.fptexas!
JUST TAKE A LOOK AROUND AND OBSERVE PEOPLE LOCOMOTE. Really?...does it take a PhD to analyze the mechanisms behind a faulty gait cycle?! .
Yet another repost: Sagittally exclusive exercises have been a main stay in the fitness industry for quite some time now. As beneficial as some systems have made these exercises out to be, they go directly against the evolutionary traits our structure is built upon. The muscles of the body are primarily oriented to create synergistic movement in the horizontal plane. This is made clear by fiber orientation, origin and insertion points and by observing the most impressive human movers in reactive scenarios. Of the muscles proximal to the spine, the largest muscles, (the ones most capable of load bearing), are all have horizontally oriented fibers for transverse rotation of the spine. The only muscles oriented vertically close to the spine are extremely small and unable to bear much load. When hundreds of pounds are placed on top of the spine, the only structures left to compensate are the discs and vertebrae, which become compressed leading to severely limited gait and breathing function, likely accompanied by some sort of pain. Along with the damage to the spine, it is also important to take in to account all of the non-vertically oriented fascial chains. If fascia that is meant to be stimulated through a horizontal stretch, but instead is crunched and crimped vertically by heavy barbell loads, it will not be able to be utilized in that horizontal fashion any longer, leading to dysfunction all over the body through the connections of myofascial networks. Lets not forget the direct trauma from the barbell balancing on your cervical spine either. Make no mistake that if your intention is to improve your mechanics on this earth, its time to break the habit of sagittal plane training, and experience the benefits of 3 dimensional movement.
