"You overheard this, 'You know why she crashed? Because she's too fat. That's why,'" host Hoda Kotb read from the gymnast's memoir.

Biles credits another one of her coaches, Martha Karolyi, for encouraging her to succeed in a more positive way.
"Martha pulled me back out on the floor. And she gave me a little bit of a pep talk," she shared. "Her pep talk gave me a little bit of an up, rather than a down."
