Pure barre, a combination of ballet, pilates and weight training has created a buzz in the workout world.
During the 55 minute class participants may look like they're not doing much, but that's the point.
Pure Barre tones muscles without high-impact movements.
The focus is on small, succinct exercises.
"We work the muscle till it's very hot and malleable, and then we go into a series of stretches so when the muscle is that warm it can change shape," explains Pure Barre instructor Bratschi Johnson.
The ballet barre helps participants use their own body weight to create resistance and works the muscles to the point of exhaustion.
Johnson says there's no age or fitness level they can't work with.
"You don't have to come in here and be in top physical condition, we can help you get in better shape, if you are in good shape we can help you get even better."
It takes about ten classes to notice a difference and for some that can't come too soon, but you'll have to feel the "barre" burn first.
The number of Pure Barre studios has doubled in the past year, with more scheduled to open to keep up with demand.
