Our Mission

We as a brand believe that EVERYONE has the power to grow exponentially in all aspects of their lives. Whether that growth is physical, mental, or emotional, we want to be the brand you grow exponentially in. 


    It's almost impossible to find athletic apparel that's actually functional, which is why we created next-level apparel. With functional features like built-in pockets (that actually work), reflective detailing, and specific fabric blends, our pieces are made to hold up in high intensity activity. Say goodbye to constantly pulling up your leggings and holding your phone on your runs. 


    You should ALWAYS feel confident, cute, and powerful in your athletic apparel. We strategically designed our pieces to be the most flattering clothing you have ever put on your body. Your new favorite leggings have no front seam (goodbye cameltoe) and the most flattering back seam for the booty, so you can workout in confidence and style. 


    You should never sacrifice comfort for cuteness. We bring you both with our unique designs and fabric blends made to move WITH you, not against you. Working out is hard enough as it is, so make it more comfortable wearing EXPNTL ATHLETICS, and watch yourself grow.

About Us

Expntl Athletics was created around the idea of fear. 

Fear paralyzes us in our tracks, controls our minds, and prevents us from growing exponentially in our lives. Maybe it's fear of failure, judgement from others, or fear of the unknown. But the moment we stop letting fear control us, is the moment we start to grow exponentially.

There’s always going to be people who judge you, moments of pain, and thoughts of uncertainty. So stare your demons in the eyes, and tell them to Watch You Grow. 

We hope that through this community, you are reminded of just how in control of your life you are. You have the power to grow exponentially in all aspects of your life. Everyone has their own unique story of growth, and we can't wait to follow along your journey and Watch You Grow.
