A members-only club that’s centered on meeting new people. The Athletic Clubs merge New York’s fun, high-octane training style with the conviviality of training with friends by way of “squads.” Through the membership, you’ll be paired with a squad based on when you like to work out and how you like to be coached. Your designated trainer will oversee progress and lead two workouts in the studio, plus you’ll get access to the gym and unlimited drop-in classes. Membership: $195 per month

A one-stop shop for all your fitness needs. Members and drop-in clients can work through a variety of modalities to get a well-balanced training regimen; offerings include a variety of strength and cardio intervals, kettlebell strength and conditioning, and an outdoor run lab. Fees and membership: From $38 per class to $249 per month for unlimited classes

Finding joy in movement and losing your inhibitions. We need to preface a discussion of this workout by saying you need to get out of your head; leave stoicism and rigidity at the door. Founded in 2013 by Taryn Toomey, the Class is a lesson in letting go and finding release, sometimes in the form of guttural screams and full-body shakes, writhes and body rolls as if you’re an inflatable air dancer outside a car dealership. Fees and membership: From $35 per class to $600 for 20 classes

A low-impact, high-intensity scorcher of a workout. In all classes, you’ll climb to the beat and work through three foundational moves, transitioning between mid- and long-range stroke length, a squat stance where your hands are fixed on the middle bar for high knees; and a sprint wherein you stay in a short- to mid-range stroke length for 10- to 30-second flurries. Fees and membership: From $30 for one class to $480 for a pack of 20

A dependable, non-intimidating workout. A mainstay in New York’s fitness scene since 2012, Fhitting Room has studios in the Flatiron District, the Upper West Side and New Jersey, as well as virtual classes. After a warmup of good mornings, jumping jacks, shoulder taps and hip openers, the instructor ran us through the Signature FHIT blueprint of the day, demo-ing each exercise with notes on proper form. Fees and membership: From $38 per class to $500 a month unlimited

A regimented bootcamp experience. You won’t be coddled in class, but if you aim for no-nonsense sweating, this couldn’t be a better workout. The studio takes over two floors, one full of squat racks and free weights dedicated to body part-specific strength classes and the other loaded with cardio machines for Training Day, the gym’s 55-minute HIIT workout. Fees and membership: From $44 per class to $349 per month for 12 months of unlimited classes

A CrossFit-tinged HIIT workout. B|X is a doozy of a workout in the very best way—challenging your cardio and endurance at a more intense level than some of the other options on this list. The main work was the cardio component, but each minute began with a strength exercise. Fees and membership: From $38 per class to $350 per month for unlimited classes

An elite personal-training experience. If you’re familiar with Dogpound because you’ve watched Tom Holland boxing and Hugh Jackman blasting out hex bar deadlifts via Instagram, it’s easy to assume that the vibe here will be elitist. We’ll set the record straight. This is exclusive, no doubt, but there’s no air of pretension. What you’ll find is a close network of clients. Fees and membership: $8,000 per year for Gold and Black tiers, via application

A zen space that zeroes in on meditation. It wouldn’t seem that HIIT and meditation could have a symbiotic relationship, but it’s incredibly advantageous to prime the body and mind for exercise. Its “Breathe. Burn. Calm.” classes have three to four blocks of work, each with three to four movements targeting the upper body, lower body, cardio and core. Fees and membership: From $37 per class to $300 per month for unlimited classes

Last-minute drop-ins and those who are always five minutes late. I couldn’t comprehend how it was possible at first, but Sweat 440 really does start a 40-minute HIIT workout every 10 minutes. The turfed studio works in batches; you move down the “line” across the room, so it’s easy for new guests to come in consistently. Fees and membership: From $32 per class to $305 per month for unlimited classes (prices based on those in the Financial District location)
