Centre for fitness
A fitness centre is a place where both people can work out, either for professional reason or for recreation. A fitness center may specialise in a certain type of sport/fitness discipline but most modern centres provide a variety of workouts. A fitness center is usually larger than an average gym, especially if it includes amenities such as pool, golf course, running tracks. They normally offer a range of group classes and individual workout programmes like yoga, zumba, boxing and so on. It provides the same machines and equipment for training and workout like in a gym, but offers a wider variety other amenities and programmes as well.
