A Personal trainer helps people exercise to develop muscular strength, muscular endurance, body composition, cardiovascular health and flexibility. The definition of healthy in this context means an absence of a disease that would affect one’s ability to exercise. Anyone outside that scope of practice should be placed in a trainer’s care after a visit to the doctor to see what kind, if any, exercise they are capable of.
It’s obvious that the number one reason people hire personal trainers is to lose weight and get into shape: it works. If you made a resolution to lose the fat and build the muscle, a trainer can keep you on track and help you realize that goal.
