is isolation work alone unable to cause growth and strength gains?

Say a guy wanted to work only his right bicept, or only his left shoulder...

Are those muscles too small and unable to work enough to get the body to produce stength and growth?

If that is true and a guy still wanted to do shoulder isolation work, would additional large muscle group work like squats help the shoulder to grow and get stronger?

Basically the goal is to fix the small weak shoulder above all else.  But if it is necessary to work a large muscle group in order to get the bodies chemical factory producing should time be spent on that as well.

Thanks.

What?

Can you repeat the question, please?

hes asking if working one muscle would stimulate growth hormones for it to grow, or does he have to work an additional large muscle group in order to stimulate sufficient growth hormones

The primary factors for growth in working muscle are not changed by performing isolation work OR cbig compound exercises... either one can make it happen.

Squats are not going to make your shoulder grow more than just doing isolated shoulder work. Don't listen to broscience.

Having said that, the most important thing to do is to figure out why the shoulder is under-developed. Once you figure that out, it's time to work on fixing whatever the weakness came from.

But dude, you know if you squat heavy your body will produce gallons of growth hormone and your whole body will get jacked!! Just squat and deadlift! It's all your body needs!
