Final answer:
Children are not natural markets for personal trainers; training for kids needs to be age-appropriate with a focus on their physical, mental, and emotional development.
Step-by-step explanation:
False. While personal trainers may find a market in working with children, it is not accurate to state that children are natural markets for personal trainers. Personal training for children must be tailored to their developmental stage and physical abilities. As children grow and develop, the need for physical activity and education regarding healthy lifestyles becomes important. Physical activity contributes significantly to a child's overall development, leading to benefits such as higher self-esteem, a healthier heart, and improved mental and emotional health.
