Life Time Fitness

Many fitness centers have dedicated yoga studios. But the one at Life Time Fitness is climate-controlled to allow for hot yoga—one of many touches that make the Rockville location of this national chain the best for group fitness.

Among the more than 90 classes offered weekly are staples such as Zumba, spinning and circuit training, but also less traditional offerings, including outdoor workouts through the gym’s run, cycle and triathlon clubs.

Members can even take mixed-martial arts classes (seriously).

Cost is $90 per month for an individual membership; initiation fees start at $50, with a $150 onetime administrative fee.
