CAPE CORAL, Fla -- Only on WINK: An amazing story of weight-loss, all for a good cause! A Fort Myers woman has entered in a national competition to gain one million dollars. But as Rachael Rafanelli reports, if she does win, the money will go to children in southwest Florida.

Fort Myers resident Bonnie Ross is pushing, climbing and running her way to a slimmer figure.

"I said anybody can lost weight! Hah not true," she laughs. The 46 year old says she's struggled with her body all her life, weighing in at 263 pounds. "When you're heavy like that, the last thing you want to do is really come to a gym," she said.

But one day she found some inspiration to face her fears and shed the weight, 70 pounds of it!  "I'm sitting waching Dr. Oz in September and he said 'I'm throwing this challenge out to America that you could lose weight and win a million dollars.' And I went great! A million dollars for the school!" she said.

if she wins, she will donate it to De Lasalle Academy, an upcoming Fort Myers school for children with learning disabilities.  She's getting some welcome help from Around the Clock Fitness.

The Cape Coral gym is donating trainers. One of them Erin Soto, knows exactly what she's going through. "Last January I actually entered the Body Transformation Challenge, and ended up winning, and went from being a preschool director into a personal trainer," said Erin Soto.

Come Monday, Ross's before and after photo will be featured on Dr. Oz. She'll find out if she is one of the finalists for the competition in April  It's something she says she hopes is an inspiration to others.
