Under Armour’s mission has been— and always will be—to make you better through the relentless pursuit of science and innovation.

And there’s this scientific phenomenon called The Köhler Effect—it says you work harder when you’re around other people than you do alone. So we brought 6 of our tribe together for a little training session. Because it’s not just the support that bonds us and makes us better, it’s the battle.

And it worked.

Each one of these women pushed harder and went further, just by being in the same room together.

But what happens when you can’t be together anymore? To motivate each other? They say confidence is

a skill. Something that can be trained, like a muscle—built up over time through repetition and resilience. It’s easy to bail after your first bit of failure, but you stand here as proof of your own persistence. And you’re lifted further by those around you— through community, through competition, through the clothes on your back. Innovations and individuals whose sole purpose is to make you better. And it’s through the help of this unique support system of others that you continue to build immeasurable confidence in yourself.

It’s not going to be easy. Anything worth it rarely is. And you’re worth it.

Make a promise. Put in the work. Claim your change.
