all these people (from bodybuilders to cross-fitters and yoga folks) just project their biases as to what is good, with very few of them having a complete closed argument as to what types of things can be beneficial or detrimental.
well sure. and yet there seems to be a clear bias, the source of which is the limited capacity of the brain to think.
it is much easier to understand what is involved in a retarded exercise like a curl than what is involved in an exercise like running.
most people who run don't understand what they are doing - they just do it because somebody told them once its good to lose weight and when they tried it worked so they kept doing it ever since.
few people will spend hours pondering what is the most efficient way to build abs lets say and come to the conclusion that it is by sprinting or swimming butterfly ( whether that conclusion is correct or not is another question ).
so running or swimming may not be the best for everybody but there are very few people for whom bicep curls are the best who instead are engaged in running or swimming. on the other hand there are many people for whom swimming or running would be best but they are instead engaged in curling because they are too stupid to know anything else.
its just that everybody knows you can get big biceps by doing curls and everybody knows you can lose weight by running. but few people know that you can shape your entire physique by sprints. most people have no idea at all that you can use sprints to train whether it is on the track or in the pool. 99% of people run and swim monotonously at a snail pace for 40 minutes and then go home.
this is because they can't visualize how their muscle is being activated during a sprint the same way as they can visualize it when curling. i couldn't understand it myself until i tried sprinting for the first time and immediately tore my hamstring. i couldn't understand how after doing heavy deadlifts every week for a long time ( going to about 95% max weight on most workouts and never running into any serious injuries ) i could tear my hamstring "just" by running ? thanks to that unfortunate incident now i understand - but 99% of people still have no clue.
ANYWAY THE SUN IS SHINING I GOTTA RUN OUT TO BIKE ...
