Like its brethren, this outpost in the Streeterville neighborhood offers guests plenty of cardio and strength machines along with free weights and Smith machines for a full body workout. It's fairly bare bones, but you are coming for the workout not the amenities.
There are locker rooms with showers and lockers. Bring all your own supplies including towel, soap and the like. You also need to bring your own lock or consider forfeiting $8 plus tax to buy a lock from Planet (no rentals).
Planet Fitness has several brands of gym equipment including Cybex, Life Fitness and Precor.
