Today we have quite an interesting variation to the much "loved" push-up. It has three points of instability, and just as the standard push-up has strong core involvement, this version has twice that need. When viewed realistically, the push-up is merely a more inclusive progression of the plank/hover. It should be noted at this point, that the exercises presented in this series are not necessarily offered as options for readers/viewers to perform, but more as general information as to what innovative lengths certain standards can be taken, and how core training needs to challenge participants beyond existing one-dimensional comfort levels.
Clearly, prior to attempting this move on the two forward placed/upper body medicine balls, this movement should be perfected to the stable floor/ground position. While as a dedicated strength & fitness enthusiast I enjoy and embrace a strong "willingness to fail", safety and natural progression/adaptation is uppermost in all my training concepts and techniques. For that reason, if you have any questions or concerns, please do not hesitate to make contact. I am always happy to discuss ideas that I put forward, and which I have now been practicing for almost a decade.
