You think you can do a biceps curl, but let's do a biceps curl where you really learn to activate the biceps at the beginning of the movement.

You're not swinging your elbow forward.

You're contracting the biceps.

Let's really learn how to bring like your pinky higher than your thumb at the top and really learn how to cramp that thing down

That to me is a skill.

It's something that requires time and it eats into recovery.

So the bigger question in here is how do you determine MRV?

And is skill and ability in being able to target muscles a factor in MRV?

Because to me, it seems like the most important factor.

Forgive the long question.

I'm just going to highlight it.

I'm interrupting you to highlight that.

If folks, if you can't contract a muscle without a weight in your hand or on your back or whatever it is, you're not going to be able to properly train that muscle.

Do you think people could do a self-test, for instance, where just on their own in their bathroom with no one around?

they could just kind of walk from calves up, just not walk physically, but just move from calves up.

Like, can you flex your calf on both sides?

Can you generate a hard contraction?

Can you do that for your quad?

Can you do that for your hamstring?

That to me seems like the most important thing to do before touching a weight or a machine, because then one can get a real sense of what kind of neuromuscular control do they have?
