Okay.

So for the busy person, this might be for you.

What, what we do in the lab is we pair these short bouts of very intense exercise.

So people do three minutes at 85% of their maximal capacity, hard as they can.

And I have stroke patients doing this.

I have 85-year-olds doing this in my lab.

They do that three times, and then they practice a task they're trying to learn, and we see significant increases in the amount that they learn in that task by pairing it with that exercise.

What do you mean?
