"I've been athletic throughout my whole life," Tonia Osborne says. "After my second child, I was feeling stagnant and wanted a challenge. There was this new thing called CrossFit, so I tried it and loved it right away." © Gail Fisher for ESPN

Osborne squeezes in at least two workouts each day -- one at lunch, one after work, and sometimes a third whenever it fits best. © Gail Fisher for ESPN

"Being a top athlete at my age is an incredible accomplishment. I started doing this for fitness, but then I thought, 'Why not push myself?' It's empowering as a woman to be able to do all that I do and be successful." © Gail Fisher for ESPN

Osborne is always on the run juggling schedules. "Most athletes get down time after a hard workout. I don't get to go relax or recover. I have to go get birthday presents, take the kids to activities -- I'm constantly moving." © Gail Fisher for ESPN

"I've really tried to make my workout schedule around when the kids aren't home, so that I can be home with them." © Gail Fisher for ESPN

"To be successful, I think you have to have that blind belief in knowing that you can win. You've done the work and put in the time, so why not me? Why can't I win?" © Gail Fisher for ESPN

"We enjoy being together and doing family things, especially on the weekends when we're all around and don't have activities." © Gail Fisher for ESPN

 "In CrossFit, there's a lot of strong-man stuff. You lift heavy stuff. It's taxing, but it really focuses on stabilization and your core." © Gail Fisher for ESPN

"The expectation is high. If I'm not first and instead am second or third, then that's what it is, as long as I feel like I did the best that I could." © Gail Fisher for ESPN

Handstand walks are one of the CrossFit elements that uses Osborne's gymnastics skills. She competed as an elite gymnast until the grind became too much. "As I got older, injuries and fear factor kind of deterred me from wanting to [compete] any further." © Gail Fisher for ESPN

The CrossFit Games are held outside of the StubHub Center in Carson, California, in the hot Southern California sun. Osborne has been training outside, but it still makes her a bit nervous. "It's an element you can't really predict." © Gail Fisher for ESPN

"The community of CrossFit really makes a difference. The support and the friendship really drew me in." © Gail Fisher for ESPN

Osborne prioritizes her family and her kids as much as possible. She says they're an active group and will go swimming, go to theme parks and movies, and love to play games together. © Gail Fisher for ESPN

"I have a great support system. I have my husband who supports me, and a live-in nanny who helps with the kids. She's been with us for six years, so she's a part of the family. They help me with my time management and the house and just the day-to-day stuff." © Gail Fisher for ESPN

"I don't want to have any regrets. I have this opportunity and I'm going to go for it." Osborne is hoping to win the gold in the master's division in the upcoming 2016 Reebok CrossFit Games. © Gail Fisher for ESPN

 Osborne is fitted with the NormaTec recovery system, a $3,600 machine that is used in the medical field on dialysis patients to flush out fluids after treatment. It is also popular with elite triathlon and CrossFit athletes for the same reason. © Gail Fisher for ESPN

"I'm a mom, a wife, an elite athlete, a professional, a PTA mom, I do it all. But like anything, it takes dedication and sacrifices at times. It's a give-and-take with everything in my life." © Gail Fisher for ESPN

Osborne works as a program manager at Panasonic Avionics. She often takes conference calls in the morning and during breaks for her workouts to fit everything into her daily schedule. © Gail Fisher for ESPN

"There are a lot of things I would never do if it wasn't for CrossFit. We have track workouts. I don't like running very much, but having people around you creates a little competition, which helps." © Gail Fisher for ESPN

"A lot of top CrossFit athletes were high-level athletes in some sport. Obviously gymnastics is one where it translates to CrossFit very easily. There are a ton of gymnastics elements that I was good at right away because of my background." © Gail Fisher for ESPN

“I’m a competitive person. I like challenging myself and having something to shoot for. I guess I'm good at [CrossFit]. When you're good at something, you want to put the effort into it and excel at it." © Gail Fisher for ESPN

 "I want to win this year. It would be the highlight of my career with CrossFit and all the hard work I've put in. Showing that I can win doing all that I do is a good story for people." © Gail Fisher for ESPN
