Any person with breasts will tell you just how important it is to wear theright bra for your body.

And, of course, they did.

AsVoxreported, the concept of a bra in itself is nothing new.

Then, in the ’20s, women in the United States started wearing actual bras instead of corsets.

So naturally, it would make sense that the sports bra would take some more time to come about.

“It began when I was a little girl who liked to avoid gym class,” Lindahl said.

Basically, “you’re all sweaty, and you had the same bra on.”

And that was an experience she just didn’t appreciate at all.

“Running for me became this joy,” Lindahl toldWBUR.

“I was not really… friendly with my body so much until I started running.

But there’s one problem.

My breasts were just uncomfortable.”

So, comfort and functionality were the name of the game.

It’s just a terrible problem.'

She said, ‘You know, why isn’t there a jockstrap for women?’

And we just laughed uproariously.

We thought that was so funny."

However, it turned out not to be all that hilarious.

In fact, asVoxreported, Lindahl ended up constructing the first sports bra from two jockstraps.

Hey, at the time that was pretty inventive.

But things like shoes, belts, and undergarments also have to serve a more utilitarian purpose.

“This was serious athletic equipment,” Lisa Lindahl toldWBURof the first sports bra.

“This was not about lift and separate.

It wasn’t about looking pretty.

It was about function.”

So really, the sports bra was important, and it didn’t need to be pretty.

And, looking back, that makes perfect sense.

But with the invention of the sports bra, that changed.

And as it turns out, it’s also the key to not being in constant pain.

According toVox,there’s a lot to consider when making a sports bra.

It can’t be too tight, as that can make it hard to breathe.

Additionally, a too-tight sports bra can mean the straps are digging into the skin in a painful manner.

And unfortunately, that replacement usually needs to happen sooner rather than later.

Audrey Kirkland, a sports bra brand manager with New Balance, toldHealththat thereisan expiration date to sports bras.

“A sports bras should be replaced every 6 to 12 months,” she explained.

“How long your sports bra stays strong and comfortable depends on the total number of wearings.”

So, if it’s been a year, it’s probably time for a new sports bra.

And honestly, that makes a lot of sense.

Well, not all men realized that at first.

Why would I put a bra in my sporting goods store?'"

Lindahl recalled in an interview withWBUR.

But, Lindahl had the perfect response.

“I would look at him and I’d say, ‘You carry jockstraps, don’t you?’

" Honestly, she was right on point, and it worked.

Before long, Jogbras were everywhere, and they were flying off the shelves.

People say that certain exercises will makes your breasts larger, while others will make them smaller.

So really, a lot of times there’s nothing you could do to prevent sagging breasts.

But only your genetics, shape, and age can determine just how much your breasts sag.
