Increased bodily pastime is an important aspect of a complete weight-reduction strategy for overweight adults who're in any other case healthy. One of the fine predictors of success inside the long-term management of overweight and obesity is the ability to develop and sustain an exercising program (Jakicic et al., 1995, 1999; Klem et al., 1997; McGuire et al., 1998, 1999; Schoeller et al., 1997).
