Powerlifting is a subculture, adds Scott.

During the set, the women picked up foam dumbbells and flexed their physiques for the crowd.

She got the call from her home gym,Quads, who automatically thought of her for the gig.

I was looking as far as I could see, but the crowd just kept going, she says.

It was electrifying and sent goosebumps down my body, she says.

We were all there for Chappell, but it felt like it was my show too.

She adds: I dont think Ill ever get that feeling again.
