After a few weeks of preview classes and a few more splashes of cheery lime green paint, the Upper East Side's newest boutique fitness spot, The Fhitting Room, officially threw open its doors this week.

The much-anticipated studio—which features a laser-focus on high intensity interval classes (HIIT)—comes tricked out with a spring-loaded floor, colorful kettlebells and props galore, plus a two trainers per small group class.

We stopped by The Fhitting Room to get our heart rates up in a daily "Fhix." Here's what you'll find inside...

Green and white is the color scheme in the well-designed bright, storefront space, which sits on the corner of Lexington and 80th Street. When you check in at the front desk, pictured here, you'll get a cold bottle of water and a green towel to mop up the sweat that is inevitably coming soon.

 

In addition to an array of colorful kettlebells, the studio (there's just one) features props like boxes for jumping, Concept rowing machines, and dumbbells. Not pictured: the benign-looking Abmats that turned a Tabata sit-up sequence into a nearly impossible feat of core strength.

 

Other tricked-out studio features: The classroom floor is specially designed with springs beneath, so that it's basically floating above the actual cement base. This make a noticeable difference when you're doing jumping jacks and high knees—you can feel it give a little as you move, which is great for reducing impact on joints. (It also absorbs sound, which is great for the other residents in the building, who would otherwise tire of Rihanna fast.)

And instead of TRX, The Fhitting Room has a similar tool, a Jungle Gym, which includes an extra, solid foot loop on the bottom, that securely grips your foot in a way the TRX can't. (That's Well+Good's Alexia and Lisa getting into position.)

 

Sessions are capped at 15 people, and every class has two instructors who circle the room offering cues and form adjustments.

In our class, head trainer Eric Salvador teamed up with Daury Dross to lead us through the daily FHIX, a "Functional High Intensity Mix" of exercises that included cardio (jumping jacks, rowing, high knees), strength training using kettlebells, dumbbells, and the Jungle Gyms, and mat work like walking planks (Well+Good's Melisse, pictured), squat burpees, and the aforementioned sit-ups.

The playlist rocked and the energy level was high, but the transitions between exercises could use some smoothing out. All classes are 50 minutes and are full-body focused.

 

Normally, we don't shoot photos of the potty, but we loved the custom vinyl art on the wall, which was done by a graffiti artist and applied by hand. The studio doesn't have locker rooms or showers for rinsing off after class. There's a small area with a bench, coat hooks, and small keycode lockers for bags. There are also bigger cubbies inside the actual classroom, for those of us whose purses carry laptops, gym clothes, and pretty much everything else we own.
