Pilates may not offer spiritual or meditative benefits, but its core-strengthening exercises can invigorate your yoga practice. Plus: 6 great exercises to incorporate into your yoga routine.

By Stacie Stukin

Through years of yoga classes, I've gamely moved intoArdha Chandrasana (Half Moon Pose) hundreds of times—balancing precariously with one hand on the floor, the other reaching skyward, and one leg shooting back from my hips. I thought I had it mastered. Then I enrolled in a Pilates class to assist my recovery from an injury, and when I came back to Half Moon, I discovered a whole new dimension to it.

Pilates not only helped me strengthen my core, it taught me how to consciously tap into the power there to create greater stability and better alignment. In Half Moon, I can now open my chest more fully and lengthen my spine in a way I had never experienced—and I can hold the pose much longer. I have really strong legs and had been using them to compensate for a weak midsection. But the deeper awareness of my core strength that I gained through Pilates has given me greater control over my movements; I discovered a center of gravity that allows me to glide in and out of the pose with fluidity and grace.

I'm not alone in bringing Pilates to my yoga mat, of course. Many yogis are recognizing that Pilates—an 85-year-old system of body conditioning designed by German émigré Joseph Pilates—is a rewarding complement to asana practice. And some, like me, are finding that Pilates's focus on building and engaging a strong core can propel their yoga practice into new realms.

Interestingly, much of Joseph Pilates's technique was derived from his study of Eastern philosophy, and many say this included yoga. In his book Pilates' Return to Life Through Contrology (Pilates Method Alliance, 2003), he wrote that age is gauged not by years but by the suppleness of the spine. He also noted that full, deep breathing is a key component to efficient movement. And a stint on any Pilates mat reveals similarities between Pilates exercises and asanas: Side Lift is much like Vasisthasana (Pose Dedicated to the Sage Vasistha), Roll Over is reminiscent of Halasana (Plow Pose), and Swimming could be mistaken for Salabhasana(Locust Pose).

But the similarities stop there. While yogis are instructed to either hold poses or flow quickly through them in vinyasas, Pilates is a rhythmic practice of precise movements repeated five to 10 times for each exercise. "There is a method to the practice, with a simultaneous emphasis on flow of movement, but a controlled flow," explains Rebecca Slovin, a certified Pilates and yoga instructor in San Francisco. By focusing on targeted movements that develop core strength, Pilates can help yogis build a stable center, lengthen the side body, and increase awareness of alignment. "Pilates helps some of my [yoga] students slow down and work deeper," Slovin says. Ultimately, she says, it can help yogis get stronger, avoid injury, and sometimes advance into poses that they hadn't previously felt were possible.

Engaging the Core 
When you hear the word Pilates, you might think of an apparatus involving pulleys, springs, or a movable platform used for a resistance workout. While equipment is an integral part of Pilates practice, the ultimate goal is to get to the mat work—a series of 34 exercises outlined in Return to Life. Done correctly, mat work is a lot harder than performing the hundreds of moves designed for the Universal Reformer, the Trapeze Table, the Step Barrel, and other types of Pilates equipment, because without the support of the apparatuses, students must rely solely on their own strength.
