What exactly is Pure Barre?

Pure Barre, started by a former dancer in 2001, is a ballet barre-incorporating exercise class that combines elements of Pilates, weight lifting and ballet into one workout. Focusing on the abs, thighs, legs and overall core, Pure Barre consists of a series of small, isometric movements that engage your smaller, lesser -known muscles. It is considered a high-intensity but low-impact workout, since no jumping or bouncing are involved.

How popular has it become?

Pure Barre now has 237 studios open in the United States, a 50 percent increase over 2013.

What does a typical class entail?

A typical Pure Barre class lasts for 55 minutes and is attended by no more than 20 people. Class opens with a light warm-up to get the body warm before stretching. It can include Planks, Bicep Curls with light weight, or Push-Ups. From there, participants move to the ballet bar, used for stabilization during work on the arms, legs and thighs. The workout ends with core and abdominal work. The class wraps up with stretching.

“Everything we do, we get your muscles to the point of fatigue or shaking,” said Lori Standen, a Pure Barre instructor and owner of two studios in Cleveland, Ohio. “The first time people have their legs shake uncontrollably, they get freaked out because it doesn’t happen with most exercises. But that’s when you know you’re changing those muscles.”

What are some other examples of moves done in class?

• Face the barre with your arms fully extended and your hands gripping the barre.
• Lower yourself into a position as if you were sitting in a chair.
• Move your body down an inch, then up an inch.
• Repeat movement 20 times.

Why should athletes try it?

For athletes looking to improve their flexibility, core strength and balance, Pure Barre can help.

“In any form of sports or fitness, stretching is important, but I think there are a lot of misconceptions about stretching prior to working out,” Standen said. “I always think of the rubber band analogy, where your muscles are like rubber bands. If you have a full, dry rubber band and you start stretching it, it’s probably going to break. But if your body is warm and your muscles are warm and you stretch them at that point, you will have a more pliable muscle and you will be able to increase flexibility.”

Core strength work is also beneficial for athletes. It improves your balance, which can be huge for both football and basketball players. Los Angeles Clippers power forward Blake Griffin credits his commitment to improving core strength with producing his best season yet. Another benefit of Pure Barre’s focus on core strength and abdominals is that athletes who commonly experience back problems can attempt to alleviate them.

“If it’s a common back injury, a lot of the time someone’s front abs are not strong enough to hold up their whole body,” Standen said. “Without the ability of your abs to help you, you put all that weight on your back.”
