Breast cancer has a new opponent -- five-time Mixed Martial Arts World Champion Egan Inoue.
These days, he's retired from the ring. But, his new foe has him back training after breast cancer took a shot at his wife.
"She had a part removed out of her. It was cancerous," said Inoue.
That's when he stepped in, but he knew preparing for this battle would take a lot more time than any of his past fight camps.
"Breast cancer -- you're fighting for your fighting for your life. So, I think it's even one step tougher," said Inoue.
And that's why he's got a small army with him. It's called Bootcamp for Boobies. The training's open to anyone every Saturday in October.
"We're all in. Everyone here is all in," said Richard Waialeale.
Participants push, pull, even crawl for the cause. The training's tough, but worth it.
"It's gotta be tougher because we're talking about life," said Waialeale.
"You never know if you're going to get cancer, but exercise before is prevention and exercise after is maintenance," said Inoue.
The bootcamp's been at it for three years at Ala Moana Beach. Funds raised this month will be donated to the Susan G. Komen Breast Cancer Foundation.
The camp's always looking for new supporters. It already has about 50 regular participants.
"They're here and everybody's focused on breaking through that quitting point," said Waialeale. "But, they're here and that's the main things. They're here, they're survivors and they're just living everyday of their life."
For some, the battle's just beginning. Others have overcome the early rounds.
But, like in any fight, anything can happen at any time. Making preparations -- that's more important.
"I would say it's like in the middle of the round, because it's not really in the middle of it. It's not really in the end because we hope we never really get to the end. You never know right? It's just being in shape and fighting and being strong the whole way," said Inoue.
