Studio K Minneapolis, Andover

Surrounded by cheeky pink carpeting and floor-to-ceiling racks of metallic-colored medicine balls, instructors at Studio K lead 45-minute fitness classes, many of which focus on seniors. With a stone fireplace nested in the corner and mirrors surrounding the walls, cozy classes whip cores into finer fettle during yoga and mat Pilates, and patrons cut a cardio rug during dance-aerobics sessions that include Zumba and Latin Dance. Studio K takes part in the SilverSneakers program, which modifies cardio and strength workouts for seated routines, making it easier for older students and reigning monarchs to participate.
