Like most professional athletes, Rose is careful about her diet, following a mostly high-protein regimen. But she refuses to obsess over it. "Overall, I try to be consistent," she tells Muscle and Fitness. "But sometimes you just have to eat what's available. I'm lucky to have good genes. And life's all about balance… If I want to eat some cheese or a doughnut, I don't worry about it. I've developed a lot of muscle mass over the years, so I make sure to consume enough protein. But I also love carbs."

Here is Rose's HIIT workout, as told to Muscle and Fitness:

Heavy Squat: 4 sets, 8-10 reps

Battle Ropes: 4 sets, 30-second reps  

Burpee to Pullup: 4 sets, 10-12 reps

Boxing: 4 sets, 30-second reps

Med Ball Pushup: 4 sets, 12-15 reps

Rowing Machine: 4 sets, 30-second reps on/off

"Although aerobic exercise is a great tool in maintaining your heart health, as far as weight loss tactics go, that steady-state run isn't the best calorie-burner," says Julia Sullivan, CPT. "And while weight training is typically the most reliable weight loss tactic when it comes to fitness type (remember though, weight loss is achieved through a calorie deficit, which is most easily achieved through diet), if there is one form of cardio that blasts calories, it's HIIT."

"I usually work out five or six days per week, depending on my schedule, with each workout lasting about one and a half hours," Rose says. "Right now, I do a little more cardio because I tend to eat more with the crazy schedule—I can't diet as much as I used to. Cardio is a good way for me to warm up and acts almost as therapy for me."

"Recovery is very important with how much we train," Rose says. "Rest for me is No. 1, because I need my seven to eight hours of sleep every night. And whenever I can get body work done, like a massage or chiropractor session, I do it."

"When starting a new fitness regime, we're often told it's important to take 'rest days' between workouts," says Derek Ball, head of sport science, University of Aberdeen. "The reason many recommend rest days is to allow the body's muscles to recover from any damage they've sustained during workouts, and to allow them to grow. And numerous scientific studies show that rest days do indeed play an important role in helping us maintain good health and fitness."

Rose started Damandyz Donutz with fellow wrestler Sonya Deville (real name Daria Berenato). "Initially, Damandyz Donutz started off as a YouTube series where the two young entrepreneurs traveled the globe tasting and rating the best glazed donuts," according to their website. "The pair recognizes that athletes, especially women are put under extreme pressure to look a certain way while eating a restrictive diet, and they combat these stereotypes to demonstrate that you can be in excellent shape while also enjoying the pleasures of life."
