Olympic legend Mary Lou Retton opened up on the serious health crisis she endured late last year.

Retton spoke to "Today" for an interview that will air in full on Monday. She talked about how dire the situation was when she was diagnosed with a "rare form of pneumonia" in October.

"This is serious, and this is life, and I’m so grateful to be here," she told "Today’s" Hoda Kotb. "I am blessed to be here because there was a time when they were about to put me on life support."

The five-time Olympic medalist is on a portable oxygen tank to help her lungs. She said she feels "vulnerable."

Her family chronicled her fight against the illness and at one point said she was "fighting for her life." Retton would then write a message on Oct. 31 assuring her fans the worst of it was over.

"I’m beyond blessed to have the opportunity to make this statement. I am overwhelmed with the love and support from the world as I fight," Retton wrote on Instagram.

"I am forever grateful to you all! I’m with family continuing to slowly recover and staying very positive as I know this recovery is a long and slow process."
