Main workout area : Our gym has a main workout area, which primarily consists of free weights including dumbbells, barbells and exercise machines. This area often includes mirrors so that exercisers can monitor and maintain correct posture during their workout. A gym which predominately or exclusively consists of free weights (dumbbells and barbells), as opposed to exercise machines, is sometimes referred to as a black-iron gym, after the traditional color of weight plates. Cardio area/Theatre : A cardio theatre includes treadmills, stationary bikes and TV displays. A cardio theater or cardio area includes many types of cardiovascular training-related equipment such as rowing machines, stationary exercise bikes, elliptical trainers and treadmills. These areas often include a number of audio-visual displays (either integrated into the equipment, or placed on walls around the area itself) in order to keep exercisers entertained during long cardio workout sessions. Personal training : There are Personal trainers who are accessible to members for training/fitness/nutrition/health advice and consultation. Personal trainers can devise a customized fitness routine, sometimes including a nutrition plan, to help clients achieve their goals. They can also monitor and train with members. More often than not, access to personal trainers involves an additional hourly fee.
