at the beginning when somebody's in their, say, first four to six months of training, that a bit more volume is necessary in order to really learn how to do the movements properly, really develop the mind-muscle connection, really understand how to train without getting hurt, and really learn what that MRV, we didn't know that concept back then, but really learn, you know, okay, I can train my legs twice per week, it's fine.

But if I go to three times, I start getting weaker in my workouts, not stronger.

If you're like me, I can train my legs once per week really intensely, but you know what?

Not every muscle in my legs is growing the same way.

Maybe I need to do twice a week for hamstrings because one muscle group is lagging.

So the reason I'm sort of spooling out this essay here is that I think there's a lot of confusion for people about where to start and where to go.

And MRV seems like it should be the kind of governing factor, the compass in all of this.

So for instance, if a client walks into your gym

And let's just say she because you train a lot of female clients.

But this could be also a man talking about chest training.

But let's talk about a woman comes in and she just says, listen, I don't want to be big.

This is a comment you hear.

But I really want my glutes to be a bit bigger.

And I would like to see some abs.

And, you know, and I – and she's –

You know, she's done cardio, done maybe a sport, maybe played some soccer, but she wants to really focus on her glutes and her quads.

What do you do to assess MRV?

Are you looking for her to get stronger every single workout?

Or do you spend two or three weeks just like teaching her the movements?

Do you spend two or three weeks teaching a guy, hey, you know what?
