Introduction: Personal trainers instruct individuals about exercise activities that improve strength, cardiovascular endurance, flexibility and bodybuilding. I listen to clients to find out personal fitness goals, then develop an exercise program, tailoring workouts to client needs. I demonstrate movements and ask clients to repeat them while offering tips on improving form. I explain safety rules and how to use exercise equipment, and I also give information on some nutritional resources, weight control and general lifestyle changes that will help continue progress.
