A "personal trainer" is a fitness professional who designs individualized exercise programs for clients to enhance their overall wellness. Their role involves assessing the client’s fitness levels, setting realistic goals, and providing motivation and guidance during workouts. Personal trainers educate clients about proper exercise techniques, nutrition, and injury prevention while tailoring programs to accommodate specific needs and achievements. Additionally, they often serve as a source of accountability, encouraging clients to stay committed to their fitness journey and maintaining a healthy lifestyle.
