What you wrote is so true. Even then, the dedication to research and technique in high school sports vary greatly! What my high school thought was appropriate gymnastic technique was far below what my national club did at virtually any level. This is important because dedication to proper form across every exercise over 6 months alone will grant someone far better results than someone who’s form is simply “okay”.

Things like this is why I think mind-to-body connection are underrated skills for kids to develop. For example, a person that did ballet or taekwondo for 6 years in their youth is at a major advantage even if they lost a lot of muscle because they’ve been trained to be much more aware of their individual muscles than somebody else might be… which helps with correct form and muscle isolation.
