One of the team members is Michelle Diaz. She will be the first one to tell you her weight loss journey has not been easy.
"About 2 years ago, I was probably at my heaviest I've been then I lost about 15 pounds. Then for the last year I've just been plateaued no matter what I was doing, what I was eating, how I was exercising. Nothing was budging," explained Diaz.
She says this challenge helped her break through the plateau and move the scale in the right direction.
