And I just remember crossing the finish line with her at the very end.

Mallory also worked as a dance instructor for Dance Your Pounds Off in Atlanta.

That girl could dance.

And she always brought that energy with everything that we were doing, Powell remembered.

She really owned the body positivity movement.

She was so spunky right off the bat, and she just danced everywhere.

She was always just enrolling everyone in her positivity, he remembered.

Then after four weeks, she was still glowing.
