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.

Exactly.

And, you know, doing that at least two or three times a week is really important to maintain your muscle strength.

And that's why hand grip strength is a big determinant of health span.

It's not just because your hand is strong, it's that you've got your upper body, which is pretty much neglected with most of the aerobic activities.

You get your upper body strong and balance training, you know, standing on one foot for a minute or longer and being able to do some touchdowns and that sort of thing.

That's really good for people as we get older because we lose some of our balance capabilities, our proprioception.
