Ellie Goulding in Tank Top Shares Boxing Workout

Ellie Goulding is packing a punch – in her workout ensemble. In a new social media post the singer shows off her incredible body – and impressive strength – during a grueling boxing workout session. “No cap,” she captioned the Instagram video, tagging her trainer, Ruth London. What do you need to know about the Lights singer’s go-to workout and everything else she does to stay fit? Celebwell has the answers.

1. Ellie Has Been Boxing for Many Years

Goulding has been boxing for years. “I start my day training at the gym,” she told People. “Somehow I’m a natural at boxing. Who knew? I feel like constantly sweating is good for getting toxins out. I like to drink and do things that a lot of women do, and that helps counteract that.”

2. She Feels Empowered

The singer explains that the workout also empowers her. “I hit hard,” Goulding added. “The idea of being physically strong and capable of defending myself gives me a real sense of empowerment, which is so different from the profound vulnerability I have when I’m by myself writing music.” She makes sure to hydrate during her grueling sessions. “I sweat like crazy,” she said.

3. Boxing Is a Great Workout for Several Reason

Why is boxing a good workout? Harvard Health maintains that boxing is a great way to build strength, improve balance, posture, hand-eye coordination, boost mood and endurance, and helps increase alertness. "This kind of boxing has many health benefits because it constantly requires you to think, change your position, and change your posture," physical therapist Linda Arslanian, director of rehabilitation services at Harvard-affiliated Brigham and Women's Hospital says."You're swinging your arms, moving the muscles of your arms and shoulders, increasing your upper-body strength. And when you're in the boxer crouch with a wide stance, with your knees slightly bent, you're strengthening your core muscles, back, and legs.”

4. Ellie Also Does HIIT Workouts

Ellie is a fan of high-intensity interval training (HIIT). “I’ll run to Faisal’s class (at Barry’s Bootcamp) in the morning. It’s only about 25 minutes from home and it gets my heart rate up enough to go in and be ready because it’s quite tough,” she told Women’s Health UK. “I’m more of a burst girl than sustained. I like it when the treadmills on dynamic and I do sprints. I prefer using my own body as weight, so press-ups, mountain climbers and burpees.”

5. She Fasts, Eats Mostly Plant-Based, and Avoids Most Carbs

Ellie is all about fasting. “I built my way up to 40-hour fasts over time (started with 12),” Ellie told The Mirror. “It helps blood sugar control and helps fight inflammation – the mother of ALL health problems.” She says she does it “very safely by having a purposefully nutritious food day the day before and after,” she added. “On the fast day, I drink high-grade electrolytes and a LOT of water,” plus tea and coffee. “Fasting is safe and beneficial unless you are diabetic or have serious health issues,” she continued. It gives her “digestive system a break,” she says. She also avoids most animal products. "I eat a lot of things for their nutritional value. The things I love for my taste are sweet things," she told Jessie Ware on her Table Manners podcast.. While she does consume some dairy now, she still doesn’t eat red meat. "I'm all about dairy….I'm not mad about coconut yogurt and all those dairy-free alternatives,” she added. "In the morning, I'll have a messy bowl which is yogurt with lots of goji berries and nuts and I love prunes and dates."
