The example was one twin brother does only curls for a year, and the other does 500lb deads for a year. Obviously the brother that did the deads gained size everywhere, including his bies, while the guy that did only curls did not grow at all, including bies.
The body adapts to the stress we put on it, greater loads on the body the bigger it has to be to adapt. You do not need to bend at the elbow and do a useless curl to stimulate the bicept.
Try doing a 2-3x body weight deadlift and then tell me your bies don't get any stimulation.
A 3x time body weight dead for me is 675 lbs. Can't quite do that lol. I deadlift 425 lbs, pretty heavy. I don't get hardly any bicep stimulation that I can tell ( no pump). My forearms go on fire though. Maybe they do get stimulated, but I don't feel it.
There's no way someone would do curls and not have the bicep grow. That study sounds iffy. Part of the growth proccess is getting a tight pump. Having the muscle expand and stretch is one of they ways it is told to grow. The actual break down of the muscle occurs at this same point, stimulating it's reasons for getting stronger and growth as well.
The original point made was that curls are useless. That's not true. Tell Arnold, or Jay or Ronnie not to do curls or tricep extentions cuz they are wasting their time. They'll look at you like you are from another planet.
Sure, doing deadlifts will be far more beneficial to the whole body vs the curl, a because you will stimulate much more growth hormone and test production. i f could only do 3 excercises, it would be deads, squats and bench. deads being my first choice.
Basically, I'm being skeptical of the study. I gurarantee I could do just tricep extenions and curls only and get them to grow. But since there are better things to do, they are at the bottom of the list, but not a waste.
I know doing the 3 core excercises will show great improvement. I know doing just curls will show some improvement. I know the combo of both will show the best improvement, greater than the improvement of just the 3 core excercises.
