A celebrity Pilates instructor says you should do these three exercises if you want to build strength

A woman in a t-shirt, leggings and socks works out on a yoga mat in a living room. Both her hands are on the floor and she is looking down towards the mat. Her left knee and shin are on the ground, while her right leg is extended behind her, parallel with the ground. Behind her are some shelves filled with decorative items; mostly plants, but some ceramics too. .

Pilates has quickly become one of social media’s favorite workouts thanks to its strength-building benefits. And while it’s known for being low-impact, it’s certainly not low effort.

Just ask Kendall Jenner, Hailey Bieber, and Forma Pilates founder Liana Levi’s other celebrity clients who have toned their physique through her popular workouts. The workouts might be known for helping supermodels get in shape, but Levi takes a more holistic approach to her instruction, helping her clients not only achieve their aesthetic goals but also educating them on Pilates’ other benefits which include injury prevention, breath control and improved coordination.

We asked Levi for her top three exercises that she recommends beginners start with—here’s what she suggested.

Sets: 1 Reps: 10-20 each side

• Begin on your hands and knees with a neutral spine.
• Reach one leg out behind you.
• Once you feel stable, reach the opposite arm in front of you. Hold for one long inhale.
• Exhale as you pull your elbow toward your knee, engaging your stable arm by pushing it into the mat. Engage your core as you do this.
• On your next inhalation, return your arm back to the starting position.
• For a more advanced version, float your supporting knee off the mat until your knee and shin are parallel to the mat underneath you.
