Planet Fitness embodies a judgment-free zone where guests of all ages and fitness levels can sculpt their physiques with myriad aerobic and strength-training options within a friendly, down-to-earth atmosphere. Patrons may tone and strengthen muscles by pushing and pulling the extensive selection of brand-name equipment and free weights. With the help of an instructor, guests can design a custom workout program based on exercise history to help them achieve their varying fitness goals. Thirty-minute small-group classes concentrate on strengthening and toning specific body parts, and full-body circuit workouts.
