Lily James is an extremely successful actress. She rose to prominence in 2015, when she appeared in Disney's live-action version of Cinderella. She then appeared in Mamma Mia: Here We Go Again in 2018. James' most notable role was as Pamela Anderson in Hulu's Pam & Tommy. James recently enjoyed a beach day, and shared some photos on Instagram. In them, she swam in the ocean in a pale yellow swimsuit. She captioned the post, "Summer lovin'." How does she stay so fit? Read on to see 5 ways Lily James stays in shape and the photos that prove they work.

To prep for her role in Pam & Tommy, James enlisted trainer, Matt Bevan, to get in shape. He shared her fitness secrets with Harper's Bazaar. "The first phase of training was based around getting Lily comfortable with key exercises; these helped her to move more efficiently, and meant I knew she was using the correct muscles and had good technique so she would remain injury-free," Bevan explains. "The exercises were all pretty new to Lily. She had trained a little in the past, and her background in dance meant she was very well coordinated which made training online a lot easier. I would show her an exercise and she would nail it straight away, which I can tell you is not always the case."

Bevan tells Harper's Bazaar that he had James make a home-gym, so she could continue her workouts. "We slowly amassed a little gym in Lily's living room and then took that to where she stayed in LA. Long bands, handle bands, mini bands, a couple of pairs of dumbbells, three kettlebells, a Swiss ball and some sliders."

James has amazing skin, and she makes sure to take care of it. She shared some of her tips in an interview with Harper's Bazaar. "I cleanse, tone, moisturise every day and night," she says. "And I love, love long baths – with as much bath salts and bubbles and oils as possible."

James shared some more of her workouts with Marie Claire. "I did boxing with a really cool guy in LA, which I love too, being physically strong like I could literally beat someone up." Health Plus Magazine reports that boxing has a lot of benefits. "When you consider the amount of focus required to succeed in boxing, even in boxing training, the fact that it can literally make your brain stronger shouldn't be surprising. But what's even deeper than its mental benefits is the aforementioned spiritual engagement and personal enhancement that result from boxing training, both of which can begin before you even throw a punch."df44d9eab23ea271ddde7545ae2c09ec

James tells Marie Claire that Bevan told her to do a lot of running, usually while she would practice her lines for Pam & Tommy. "He would make me do all my work and reading my script on a running machine." Valley Oaks Health states, "The positive impacts of a run extend beyond the finish line and into bedtime. Studies show that aerobic exercise such as running can significantly improve the quality of sleep, even for those suffering from insomnia. Running has also been linked to a reduction in daytime drowsiness, meaning you'll have more energy for your day and less fatigue to fight through."
