What about the weighted vest?

Yeah.

So the funny thing is like rucksacks have been around for years.

Exactly.

The military uses them to train their members, their athletes.

So the data on weighted vests is it's it's the problem with it is that some of the studies are very small and then some of the follow up studies are on even a smaller portion of the original study.

And they're usually using mixed methods.

So they're not only wearing the weighted vest.

The subjects are also doing some strength training and some other things.

So we can't attribute necessarily improvements in bone density to just using a weighted vest.

But there are some studies that indicate there are improved parameters of balance and strength and things like that.

And I like it for cardiovascular exercise.

It adds to my walk.

If I walk my dog, I put on that or a rucksack.

If I wear a rucksack, I feel like I get a little bit more maybe core work.

But so it's...

They're certainly not harming people.

I like it for balance training too.

And there's so many things that I like to tell people are the opposite of disuse.

And now we think about data on things that stimulate bone density and jumping.
