• Meghan Trainor revealed that working out with her boyfriend helped her enjoy exercise.
• Although she initially wasn't extremely fond of fitness, she said she became "obsessed" after seeing both physical and mental benefits.
• Exercising with your partner can improve your fitness and your relationship, too. 

Finding a workout you like and can stick to can be almost as difficult as finding a compatible romantic partner. Singer Meghan Trainor, however, has lucked out on both counts. 

The 23-year-old recently revealed to ET that she has found a new love for working out, thanks to her boyfriend, former "Spy Kids" star Daryl Sabara.

"He taught me how you can feel better if you eat healthier and exercise, even mentally," she said. "After my second surgery, I went into this dark place and he was like, 'You want to workout?' and I was like, 'No, but OK.' But now I love it. I'm obsessed with it, and I've never felt better." 

Trainor said that Sabara changed her entire life. She recovered from two vocal cord surgeries with his support and now has his support when it comes to health and fitness. Trainor has especially found a love for the program T25, a full-body workout routine you can do at home.

It's no secret that exercise is good for your health and mind, but doing so with a romantic partner takes the benefits up a notch.

According to Psychology Today, working out together can benefit both your relationship and your fitness level. Exercising with your partner can specifically "boost your energy output" and thus make your workouts more efficient. Sharing and caring about similar goals is motivational too. One study found that how you talk to your partner about exercise can improve their performance and help them reach their goals, according to Psychology Today. 

US News reports that exercise can also increase the attraction between a couple because exercising results in sweaty hands, a racing pulse, and a release of endorphins. 

"Some of that arousal can be associated with your partner, which does nice things for a relationship," Theresa DiDonato, an associate professor of psychology at Loyola University Maryland told US News. "Men and women are more likely to make a positive health behavior change if their partner does too." 

Being on the same page as your partner fitness-wise has other benefits. Psychology Today also reports that when couples exercise together, they coordinate their actions and engage in "nonverbal mimicry" helping them bond and feel closer emotionally. 

Working out with her boyfriend has definitely helped Trainor, and although she hasn't always loved fitness, now both she and her relationship can reap the benefits of exercise.
