That is why you will never find more than five people at a time working out under the expert eagle eye of Zareen Watson, a multiple-certificate holder in various aspects of fitness. When a client walks in through her door, he or she can expect and will get a tailor-made training programme that will bring out the best in his or her body. But while every gym offers personalized training, Watson Fitness’ very approach to fitness makes it stand apart from the rest.
