Stability is the foundation, no energy leaks.

@@mr.t244 Read what I wrote first, and then you get to comment on it so we can have a proper discussion. Your body is about 30% efficient when it comes to mechanical efficiency so the idea of "no energy leaks" is as futile as your poorly articulated comment. But on the other hand, thank you for sharing your opinion - much appreciated.

@@josipvran Honestly I spent 15 mins writing up follow up argument but yt decided to give up on me, so I won't write anything besides this. If your way of thought wotks when training your clients, athletes, general population, go with it. All Im saying is there are certain principles that are higher in hierarchy of importance than others, postulates so to speak. You do not exert most efficient movement pattern with poor base of support, stability. We can have same force in muscles in the throw let's say hypothetically, if your ipsilateral movement pattern in this case is better by certain principlrs, more fluent dynamically, you will beat me, every single time. Longevity of athlete and their patterns are also correlated, once on the top succeeding with incorrect patters are not succeeding because of them, they are succeeding in spite of them, genetics are a wonderfull thing and to some teaching the correct movement pattern will do more harm than good if they are already well developed athlete. Check Roger vs Murray serve, slow it doen check Murray patterns, tonus of quads, missalingment, his hip injury eventually. Variability is good, yes, but give your body an option to do certain movement incorre ctly or not do the movement at all, it will do the movement incorrectly if enough force is applied and obviously if your tendons, ligaments can keep up. Repeat it enough times, that pattern will become stronger, for sure, but that is reinforcing wrong pattern right from the getgo, its reinforcing compensation. So why not apply variability while having some.principles in mind rather than applying variability for the sake of it. Your body adapts to long sitting by going into kyphosis of thoracic spine, its easier obviously to have loading on the spine and passive structures rather than having to actively have muscles engaged in correct position, by your analogy, kyphosis is 'better' here than normal posture that is described by golden line for example ? I don' think so. And lastly, no, most efficient movement patters are not 'not stable', they are stable. Efficiency should have time span in mind along with achievement when talking about athletes, not temporary efficiency that will go down the drain when injuries start piling up, and as I said, some top tier athletes succeed despite false patterns, not because of them. And lastly regarding that last comment 'most efficient movement patterns are not stable, they are highly variable', having some small degree of variability in mind, once you go past that, its just reinforcing bad movement pattern that your body goes to once it cannot sustain the correct one anymore (different for everyone, body is seeking the weakest link in the chain), so again, if enogh force is applied, lets say last rep of last squat, so enough force, your connective tissue doesnt give out, yea u gonna perform probably shitty ass squat if you let variability get.in the way of efficient movement too much, too often. This is as broad topic as it can get probably, I could end up writing essays here but I neither have the will power, time, nor the reason, this is just food for thought. English is far from my mothertounge, some mistakes or not the best expressions are probably here, I won't comment anymore, cherrs.
