The primary job of a personal trainer is to provide knowledge, keep track of your fitness level, and offer encouragement. The success of your personal training depends in large part on your own goals and your own motivation. A personal trainer can help you progress, but having appropriate goals and expectations for your individual training sessions are very important. Women as a group tend to underestimate the time it should take for them to lose weight and get into shape. It’s important to set realistic goals, share them with your trainer and together work to achieve your end result.
