From starting her acting career as an uncredited actress at ZMD: Zombies of Mass Destruction (2010) to winning Glamour Woman of the Year in 2024, Sydney Sweeney has come a long way. However, after starring in Christy, suddenly everyone wants to know: How does the Euphoria actor stay so fit?

Sweeney stays prepared for long filming schedules by relying on workouts she enjoys and meals that keep her steady through demanding days. Her approach isn’t built on strict limits, but a lifestyle shaped around what actually works for her body and her career. So let’s dive in and take a closer look.

Workout Routine: Training That Keeps Sydney Sweeney Ready for Any Role

MMA for Discipline and Power

Her fitness foundation comes from mixed martial arts. She began MMA at 12, drawn to grappling and boxing. The training taught her structure, focus, and the ability to build real strength. By 18, she even stepped into her first competition, carrying forward the discipline she learned on the mat.

Morning Workouts Set the Tone

She prefers to train early because it clears her mind and anchors her day. Morning movement helps her stay focused during filming, travel, and press commitments, and running is often her go-to when she wants a simple way to move and reset.

Pilates for Full-Body Strength

Pilates, especially Solidcore, plays a major role in her routine. Its slow and controlled movements help her build strength, maintain balance, and stay connected to her form, something she depends on when preparing for physically demanding roles.

Outdoor Activities to Stay Consistent

When she wants a break from structured workouts, she heads outdoors. Hiking is one of her favourite ways to stay active, often with her dog, Tank. She also mixes in water skiing and other outdoor activities that build endurance while keeping her energy up through enjoyment rather than pressure.

Diet and Nutrition: Fuel That Supports Her Lifestyle

Hydration as the Main Rule

Her top wellness practice is hydration. She sticks to water, aiming for at least two and a half litres a day, sometimes adding electrolytes during heavy training periods. “Ever since I was 12 years old, I was like, ‘I'm just going to drink water,’” Sweeney told Women’s Health in February last year.

Balanced Meals Without Restriction

Like any fitness-focused Hollywood star, Sweeney’s meals focus on lean proteins, eggs, berries, and carbs that give her steady fuel. That protein intake goes up when she’s preparing for a particularly physically challenging role. 

For her role in the boxing biopic Christy, her diet shifted dramatically to include high-calorie foods like milkshakes and peanut butter sandwiches to support intense, three-a-day training sessions that built muscle. However, she doesn’t always eat like an athlete, allowing space for flexibility in her diet.

Moderation and Treats That Fit Her Lifestyle

She avoids strict food rules and allows space for the things she loves: Kit Kats, ice cream, sour candies, especially since she doesn’t drink coffee. Classic comfort meals like mac and cheese still show up in moderation. So what can you learn from Sydney Sweeney’s method?
