Absolutely, but it just matters whenever you start.

If you start training in your 80s, I think there's even evidence in maybe 90-year-olds, they can grow muscle.

Awesome.

But the caveat is that you start... Andrew, you and I won't be able to have this much muscle when we're 90, obviously.

I hope you're right.

Well, maybe we will.

Maybe you'll figure out these with your protocols.

But my point is...

If you start training when you're 15 and you train optimally throughout your whole life,

There will be a point where you peak with your muscle mass and then there'll be a point, but the point is it's further than people think.

People used to think, well, you'll probably start losing muscle mass in your 30s.

No, it's probably more like in your 50s, you can maintain all of it.

But if you haven't started lifting, you will absolutely grow muscle.

Will a 70-year-old who starts training for the first time grow muscle as much as you will

when you're in your 20s.

No, but you still will grow.

It's just blunted a little bit.

You know, age tends to dull everything, but you can absolutely grow and you should absolutely start.

Strength training during pregnancy is very well researched.

It is absolutely something you should do.
