Gyms that promote exhausting workouts have a new pitch for members: not moving a muscle.

Fitness centers increasingly are offering classes that feature meditation. Organizers say they’re responding to the demands of stressed-out members seeking introspection and relaxation in a place they already frequent.

Antigravity Cocooning, a class launched in January at a Crunch Gym location in New York, puts members in sling-style hammocks that hang from the ceiling.
