Backblast photos from July to date for Saturdays ONLY.

Do you notice something?

Some of the same women show up day in and day out to Saturdays. They show up consistently because they know what it feels like to show up and just feel a breathe of fresh air. The lightness other women can bring. The vulnerability they can share. The friendships and laughs along the way.

If you are like us, life is hard. Every day some new hits us and we find ways to manage. Social media is riddled with post of terrible storylines and heartbreak.

This is not only to break up your feed with some smiling faces, but to show you that the door is open if you’re looking for more.

You don’t have to be in shape to start. You just have to show up.

At FiA, we’re building more than stronger bodies. We’re building confidence, friendships, accountability, and a community that cheers for you on your best days and your hardest ones.

Every workout can be modified.
Every woman is welcomed.
Every first workout is the beginning of something better.
We have too much fun sometimes.

If you’ve been waiting for a sign… this is it.

Come sweat, laugh, grow, and find the community you didn’t know you were missing.

📍Women 18+
Every workout is always FREE.
Tag a friend and come see what FiA is all about!
