The phrase young, weak and underdeveloped keeps coming up within the same phrase as max strength. If an individual is that far behind, the weight room is the last place where to make gains. General strength should take precedence above everything else before the introduction of max strength. Introducing max strength to a kid like that is a recipe for disaster . . . so it is a poor example.
The myth of strength before plyo’s needs to be squashed as well. Sprinting is plyometric in nature, yet a kid will sprint when he is a 6. Plyo’s are more of a problem when used with improper form and abused. High school girls triple jump all the time without ever having touched a weight in their life. Girls long jump in middle school without having lifted. More issues come from poor posture, improper protocol, . . . rather than plyo’s.
We spend 85-90% of our season developing power and about 10-15% on MxS yet strength levels are more than adequate. Actually, the more I move away from MxS, the better my athletes have done on a whole.
