A personal trainer is an individual certified to have a varying degree of knowledge of general fitness involved in exercise prescription and instruction. They motivate clients by setting goals and providing feedback and accountability to clients. Trainers also measure their client's strengths and weaknesses with fitness assessments. These fitness assessments may also be performed before and after an exercise program to measure their client's improvements in physical fitness. They should also educate their clients in many other aspects of wellness besides exercise, including general health and nutrition guidelines. It is very important that a trainer takes their time to evaluate a clients personal life outside of the gym. This way, personal trainers can figure out what kind of stress their client may be putting on certain areas of the body during their every day lives. Qualified personal trainers or certified personal trainers (CPTs) recognize their own areas of expertise. If a trainer suspects that one of their clients has a medical condition that could prevent the client from safe participation in an exercise program, they must refer the client to the proper health professional for prior clearance. view job details
