King works with trainer, Jason Walsh, to help her stay in shape. He opened up about what it is like to work with the actress to Shape Magazine. Walsh says that King has a good approach to exercise. "I think a lot of it had to do with attitude," he says. "And eagerness to listen and want to get better, stronger."

King talked about her wellness to Byrdie. She says that working out is how she relieves stress. "This sounds odd, but I didn't know that I was the type of person that needs exercise to not feel wound up. If I'm feeling pent up and I don't know why, if I just move my body, then all of a sudden I'm so much more relaxed."

King tells Byrdie that she doesn't like to compare herself to others. Instead, she focuses on herself and what she needs to do. "I think not being able to make fun of yourself comes from comparing yourself to other people too much. It's hard not to. I'm human. I do it, too. Whether you're in the public eye or not, there's so much we have to let go."df44d9eab23ea271ddde7545ae2c09ec

A lot of people like to make personal goals. King is not one of them. She explained her reasoning to Byrdie. "You'll never be happy. Either you'll reach that goal and then just be thinking about the next one, or you won't reach that goal, and then you'll be miserable forever."

One type of workout King likes to do is weight training. She shared this video on Instagram of herself at the gym. In it, King is seen doing deadlifts with a large barbell. She captioned the video, "Personal record 140 lbs." Weight training, also known as resistance training, can provide a number of benefits for both men and women, including:

1. Increased muscle strength and size: Weight training can help you build muscle mass and strength. This can be particularly beneficial for older adults, as muscle mass naturally decreases with age.
2. Improved bone density: Weight training can help increase bone density, which can help reduce the risk of osteoporosis, a condition that causes bones to become weak and brittle.
3. Enhanced athletic performance: Weight training can help improve athletic performance by increasing strength, power, and speed.
4. Improved insulin sensitivity: Resistance training has been shown to improve insulin sensitivity, which can help reduce the risk of type 2 diabetes.
