While feeling the burn during a workout is generally a good sign, feeling the burn while sitting on the sofa means your sofa is in the fireplace. Engage in controlled, constructive body burning with today's Groupon: for $75, you get one month of unlimited adult fitness classes at Work it Out, in Hoboken (a $250 value).

Work it Out helps patrons shed pounds and tailor their muscles to a trimmer form with more than 13 types of adult fitness classes held in a fully equipped, state-of-the-art facility. While spin classes burn calories with intense cycling workouts in a private, eco-friendly wood room with bamboo flooring, Pilates sessions flatten stomachs and strengthen core muscles in a spacious 900-square-foot mat room with spring floors. For twinkle-toed fitness fanatics, Work it Out boasts barre classes that blend ballerina moves with yoga and strength training for a full-body workout, as well as a two-hour pole-dance workshop for getting fit while having fun learning flirty pole moves that come in handy during extreme-pogo competitions.

All classes are held in Work it Out's comforting, private studio spaces, with sessions scheduled throughout the day, accommodating busy schedules of work, child rearing, and competition in the vicious underground-baking circuit. Groupon holders may double up, packing two classes into any given day.

Reviews

Hoboken Patch and Hoboken411 both featured Work it Out:

• Everything is provided, from towels to yoga mats; first-timers get a free water bottle to fill up with the delicious lemon water; the lockers are right out in the open, keeping the community feel alive. Even the bathroom has a boutique feel. There are cups overflowing with gum and hair ties; locker rental is free and class sizes are kept small. – Danielle Elliot, Hoboken Patch
