Voices from the floor
Why athletes come back, year after year.
“I came for the competition and left with a community. I've never felt so backed by a room full of strangers.”
“My first comp ever and everyone was cheering for everyone. I've already signed up for the next one.”
“Strong, sweaty, smiling all day. The Butterfly Effect changed how I see myself in the gym.”
