Now, your heart aging, you can accelerate it if you are smoking, if you are sedentary, if you eat a lot of added sugar.

All these things accelerate the aging of your heart.

So as we age, our hearts get stiffer and our hearts shrink.

And that really predisposes us to cardiovascular disease, the number one killer in the United States, as well as many other developed countries.

So he took these individuals and put them in two groups.

One group was going to get the exercise treatment, and the other group was a sham control, sort of a placebo, and they were doing sort of stretching yoga-ish type of exercises, enough to make them think they were getting the intervention, right?

So the individuals that got the treatment, the exercise treatment, I mean, this is a progressive program.

It's two years long.

You can't just take someone who's never really exercised and just immediately make them start doing five hours a week of exercise, right?

It's too much.

So it was a progressive loading.

These individuals over the course of six months sort of worked their way up to actually doing five hours of exercise a week.

A large amount of that exercise was cardiovascular exercise where they were jogging.

They were on a stationary cycle, getting their heart rate up to the point where they could have a conversation, but it was very, very breathy.

And then they also incorporated what's called high-intensity interval training.

Have you heard of this?

Of course.

This is where you're pushing yourself a little bit harder where you can't have that breathy conversation because you're working so hard.

You're getting your heart rate up to 80% max heart rate or more.

And then you recover for a period of time, and then you do it again.
