Any.

So even if it's a walk that's relatively brief without any fast heart rate or sweating, that's good.

But the more the better to a certain point.

It doesn't have to be extreme.

But we're talking about at least five times a week, ideally, 30 minutes of aerobic activity.

That would be brisk walks or cycling or elliptical or treadmill, running, jogging, all these sorts, swimming.

30 minutes five times a week, that's to strive for.

It doesn't have to be with a heart rate monitor.

It doesn't have to be where you're working up, you know, torrential amount of sweat.

The extreme isn't really proven, as I review in the book, about how far, how nuts you have to go with this.

But as long as you're getting a good workout and having some sweat is an indicator without having to worry about your heart rate or whether you can talk or not.

So that's one thing.

But the big change in recent years is the new data about resistance training and balance training.

So as we get older, we lose muscle mass.

And that's not good for healthspan.

And so that the ideal thing is some resistance training.

And that could be, you know, with bands or, you know, pushups and sit ups and, you know, planks and lunges and that sort of thing.

It doesn't require it.

It's free.

I mean, it doesn't require any expensive equipment.
