She relocated to Cookeville, Tennessee, home to the famous CrossFit Mayhem gym owned and operated by Froning, who has won the Games as an individual three times, and as part of a team five times.

“There was a lot of pressure at the semi-final because I left my entire life in Hong Kong to train in the States,” Campos said. “But, I just new I could make it because of the result last year and I had dedicated the time and trusted the work I put in.”

It’s certainly the perfect environment in which to push yourself – five athletes from Mayhem have qualified for the Games this year, and three teams of four as well.

“Mayhem’s the best gym in the world,” said Campos, who will return to Hong Kong in September after the Games, which take place in Madison, Wisconsin. “The programme is amazing, and the facility is like all of Hong Kong CrossFit gyms combined. It’s like a dream, like a playground.

“In Hong Kong, I had no one to train with. I was doing my own thing. I did things in my own time, I trained between classes. But at Mayhem now, everyone does the same programme.

“There is always someone who will beat you in something. The push is there. You are going hard all the time. They beat you and then you beat them. It’s back and forth. It’s really cool, the experience is really nice. I love it.”

The biggest difference for Campos has not been the physical training, but her mindset.

Last year, she underperformed in a couple of events and allowed it to affect the rest of her performance. She was filled with negative thoughts, telling herself “I’m so weak, I’m not good enough”.

“Mindset was something I knew I had to work on – how do I face the competition floor and just focus on each event, just one at a time and not think about ones I hadn’t done well on?” she said.

At CrossFit Mayhem, they offer a course called “Mayhem Mindset”. Campos wrote down all of her personal values and then completed mental challenges each week to learn how to focus on her own performance and forget about other competitors.

“You can’t control adversity but you can control your response to it,” she said. “You really do look within yourself – what are your values, what is your purpose? You put it in words what it means to you. You get to know yourself in a very deep way and that way you know how to respond if any adversity comes you way.”

There are 10 values on the programme but the ones that jumped out for Campos were trusting the hard work and being grateful.

“When you write it down, every day you look at it and you realise you are doing the right thing, doing what you love. And if you are doing that, there is no way it is not going to work out,” Campos said.

Now, Campos has a specific word she associates with each movement. If she has to do wall-balls, she thinks about hitting the target. If she has to do chest-to-bar pull-ups, she focuses on the word “breath”.

“Going onto the floor, it’s now not about what are people are doing, or other external things I can’t control,” she said.

Froning is often in the gym and has been a huge help too. He spots specific but subtle ways to improve athletes’ movements and has useful advice on how to approach a workout.

“He is super helpful, I always trust what he has to say. Hopefully, now I’ve made the Games I get to train with him even more,” Campos said.

With qualification for the Games now secured, Campos will refocus on the next task at hand.

“I need to make sure I’m doing my best for every single event and not focus on what others are doing,” she said. “This is the big league, and I really want to represent my country the best way I can and have some fun doing it.

“I want to get in the arena and look at the crowd and say to myself, ‘I deserve to be here’. To give them a show, do my best work and give some work for the other girls too.”
