Singer Meghan Trainor may be known for being "All About That Bass", but she's currently all about exercising as she showed off her new slimmer figure on Instagram.

The 23-year-old shared to ET that her boyfriend, former 'Spy Kids' actor Daryl Sabara, has changed her outlook on health and fitness.

"I work out so hard," she shared. "I've been working on my health [with] my boyfriend and, yeah, we eat good and we work out, like, every day."

"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."

The singer struggled this year as she recovered from two vocal cord surgeries, but she credits his support and patience as her success, as well as her motivation to exercise.

Studies have proven that 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. It's also known to increase the attraction between partners, as exercise releases endorphins.
