2. 305 Fitness — NYC; Washington, D.C.
Beginners and pros feel like superstars at this studio named for Miami's area code, where a live deejay spins pop and hip-hop. Tone with dumbbells between all-out dance sessions. —Kristin Canning
3. AKT — NYC Area
Founder Anna Kaiser (trainer to celebs like Shakira) pays equal time to high-octane sequences and strength moves, so even rhythmically challenged clients score a great workout. Dancing in the midtown studio? There's a glittering disco ball, plus a photo booth for sweaty selfies. —Jenna Autuori-Dedic

Katia Pryce creates high-energy sweat sessions featuring hip-hop and ballet mash-ups punctuated by body-weight moves like push-ups. What sets it apart besides the varying levels of difficulty? The saucy, sexy vibe. —Abigail Libers

This nonstop 55-minute class with Nicole Winhoffer blends countless reps of strength moves (to fatigue your abs, arms and glutes) with fun, easy-to-follow dance routines. —Elyse Roth
8. PulsePDX — Portland, OR
With a stage and flashing lights up front, this studio feels like a hot concert venue. Power through hip-hop, salsa and merengue moves while a deejay plays Top 40 tunes. Clients are encouraged to jump onstage to show off their skills. —Juno DeMelo

11. Body & Soul — Miami
Channel your inner dancing queen with Videosync, a high-energy class designed to look and feel like a music video. This swank 10,000-square-foot studio is blinged out with state-of-the-art equipment (think Cybex, Precor, Assault Bikes, Concept2, and Rogue), a nightclub-reminiscent sound system and lighting, a lavish locker room, The Health Nut Cafe, Ohm Boutique, and valet parking. —Ana Mantica
12. Dancinerate — Los Angeles
Ilyse Baker's classes mix moves from jazz to old-school funk to Broadway, with a playlist featuring Beyoncé, Michael Jackson, Sam Smith, and Adele. Baker's beginner-friendly attitude means she breaks down the steps slowly several times before speeding up. And there's always something new: With occasional exceptions for old favorites, the routines change constantly. —Courtney Rubin
13. Inner Me Studios — Houston
Start the hour-long Urban Aerobics class with stretches, then dance to current chart toppers and classics (the Charleston, anyone?). You'll also target abs and legs with mat work, then finish by showing off your moves in a dance circle. —Holly Crawford
14. Millennium Dance Complex — Los Angeles
Janet Jackson, Justin Timberlake, Britney, and Usher all have taken classes here (JT's chief choreographer is a teacher). One favorite: SALT — Sculpting Aerobic Lengthening Technique — which mixes Pilates, strength training, aerobics and dance. —Courtney Rubin
15. Vega Dance + Lab — Portland, Oregon
Classes are held in an industrial warehouse with one wall covered in graffiti. Expect an instructor clad in high-tops and Fetty Wap blasting from the speakers. You'll begin with a rapid-fire series of push-ups, triceps dips, and crunches, then spend the rest of the Cardio Funk session learning a challenging hip-hop routine. Toward the end of the hour, you'll split into two groups and take turns performing while your fellow students cheer you on. —Juno DeMelo
