A personal trainer is an asset in the world of weight loss - and the good news is that they are a fixture at almost every gym. The reality is that it is often a better choice to have guidance when you are trying to lose weight and get fit. Another advantage of having a personal trainer is that some of there is usually assistance with making meal plans and the added incentive to stick with the plan.
A personal trainer's job is to be a guide for his/her students throughout the weight loss program and should have the courage to get you back in line. There should be no fear of reprisal from the student because this relationship is often the true definition of tough love.
