Fitness studio Crowbar Cardio opened at Greenville and Belmont avenues two months ago — reminding us to squeeze back into our now-tighter workout pants.

At Crowbar, it's all about low-impact but intense exercise routines. Co-owners and longtime friends Karen Soltero and Molly Setnick believe in "wrecking your workout, not your body." That comes as a relief to people with joint issues or those of us who simply don't want to feel like we are killing ourselves during a workout.

"We were very aware of what impact sports can do to your body," says Soltero. "You should be able to do fitness your whole life, without damages."

And don't be fooled by the 70-year-old who, Soltero says, "comes to class and kicks everyone's butt." At Crowbar, you're in for a sweaty workout.

So how do they pull off this idealistic workout meant for just about everyone? The studio has some cool toys: RealRyder bikes, Indo-Row machines and a barre.

Here's the breakdown of the core classes:

• Crowbar is the only studio in Dallas with RealRyder bikes, which are like stationary bikes, except they move from side to side. Cycling on one of these fun bikes, in a 55-minute class, provides an even greater heart-pumping workout than the standard stationary bike. And, instead of your body absorbing the shock of the ride, the RealRyder takes the heat.

• In an Indo-Row class, you race at a high speed in teams. The Indo-Row goes through the same motion as a regular row machine, but you pull a cable that moves a blade through water, instead of a blade that turns a fan.

• Barre classes are taught by professional dancer and fitness instructor Vlada Gorbaneva. Unlike most barre classes, which focus on sculpting and toning, each hour-long Crowbar class fuses dance and fitness for a fat-burning, energy-inducing routine.

Crowbar offers five to seven classes a day. You can register online, whether it's a core class, combo class — such as Triple Threat, which combines all three core classes, and Crow, which incorporates both the RealRyder and Indo-Row machines — or a circuit-training, boot-camp-style class.

Because we're sometimes weak at the knees but always in need of a sweat-inducing workout, we're adding Crowbar to our hot list of fitness studios.
