Charli relies on her workouts to give her the energy to perform. "I perform in a really high octane and energetic type of way. So, for me, it's important to keep fit. Also, I find that if I don't exercise, I feel less awake. I try to workout five times a week because it really lifts my mood and makes me feel more positive. It's important for me to stay balanced."

Charli relies on drinking lots of water for health, beauty, and getting over jetlag. "I get kind of lazy when I'm on tour," she says. "It's a lot of face wipes — I like Johnson's. It's made for babies, but that's what my mom used to buy. My mom is terrible with makeup, so no words of wisdom there, but the one thing she does tell me is to drink loads of water."

Charli never skips her yoga sessions, even when she's on the road. "I always take a yoga mat everywhere and do body-weight exercises," she says. "I try to do that before each show. It really works for me."

Charli says performing is a workout in itself. "Performing is my favorite workout," she says. "I do go pretty hard on stage. The gym is not my scene. I did an Insanity workout on tour for a while. It was hilarious… Does pizza-eating count as a sport?! That's good for biceps, surely? Lift and bite!"

Charli enjoys pizza and fried chicken, but makes sure to balance it out with healthy food too. "I love sushi, but I also love pizza," she says. "Let's just say it's balanced!" "All types of fish contain protein, but only some have omega-3 fats. These healthy fats benefit your heart by reducing the risk of cardiovascular disease or blood clots. Additionally, they provide brain boosts and have anti-inflammatory properties. Mackerel is a good source of omega-3 fats, as is salmon, tuna and eel," says the Cleveland Clinic.
