By following the PT's guidance, the result can be the ability to train longer and harder than if you train by yourself. You may push yourself harder with a PT by your side as a guide and cheerleader. The PT can help you reach your health goals and attain a higher fitness level much quicker.
The important characteristics of a PT are approachability, friendliness, and an ability to make you feel comfortable during the training session. You will likely see your trainer every week, so picking someone you can connect with is the best approach.
A good PT should be willing to answer your questions or concerns. They challenge you but should not push you to injury or pain. As a good PT, refrain from recommending fad diets or supplements. They provide you full attention and don't waste your time in excessive conversation or texting during your training session.
