If your goal is to lose weight, then yes, your personal trainer can help you lose weight. This really comes down to the “why” of deciding to exercise and work with a personal trainer. Finding and understanding your goals is one of the most important things a personal trainer should do with you. The initial appointment should spend a significant amount of time asking you questions to define your goals and set the expectations. If this is not done, then the chances that you’ll be disappointed or worse give up increases dramatically.
