1. She Maintains Her Motivation

Staying motivated is crucial for success. With an intense workout plan, it can sometimes be difficult, but she sticks to it. "I think it's probably best to work out in the morning to get it out of the way," Lily said. "My ultimate top tip is to drag yourself, even if you have to roll yourself out of your bed and into a sit-up – it's really not that bad once you start." Lily said she just keeps telling herself “you can do it.” It’s really when you push yourself that the real change happens in your mind and body.

2. She’s Tough and Disciplined

She really dials in, maintaining a strict diet with herself. "I had to be really strict with myself, I knew if I cheated myself with chocolate and wine then it wouldn't work", Lily said referring to her diet for Fast Girls. "I had to give up everything I love. We couldn't drink, eat chocolate, have sweets or desserts. But you know what, I got well into it... It's amazing to see how much better you feel and to see the change in your body."

3. Cardio is Key

Sweat sessions really prepared Lily‘s body for her big roles. "I worked with this amazing trainer, Matt Bevan, who worked with Daisy Ridley as well,” Lily explained. ”He worked me so hard and I got really fit." Her trainer used boxing and running for her cardio. "I felt really athletic, which I hadn’t done for a long time and there was great confidence that came from that... I feel less self-conscious on a beach now. It was really wonderful to feel like that, to feel so in my own body."

4. She’s Consistent With Her Workouts

Lilly really stresses that consistency is key. She explained to Cosmo that preparing for her role in Fast Girls was really intense, teaching her quickly that hard work pays off. "It was very intense – we had about six weeks of training before the film even started," Lily explains. They trained five times a week with regimens including strength training, running, circuit training, and more.

5. She Walks and Bikes Everywhere

“I also just started cycling again,” Lily explained to Shape. “I cycled everywhere when I moved to London, until my bike got stolen. Then I started taking Ubers. Recently, I got my bike back, and that’s been such a gift. It’s my bit of freedom to ride without having any direction stuck in my mind. It helps me stop overthinking and just connect myself to the present.” She informed British Vogue that walking does wonders for her, too.
