A Personal Trainer is a person who helps people exercise. The scope of practice for a personal trainer is to enhance the components of fitness for the general, healthy population.
The five classic components of fitness are muscular strength, muscular endurance, body composition, cardiovascular endurance and flexibility, although there are subsets like power, skill and speed.
Anyone outside that scope of practice should be placed in a trainer's scope after a visit to the doctor to see what kind, if any, exercise they are capable of.
Personal training is available to anyone - if you are an experienced athlete or if you are just starting with your exercise programme. Please feel free to enquire about this service.
