Step-by-step explanation:
Physical fitness refers to the ability of the body to carry out daily activities without undue fatigue and with ample energy to engage in leisure activities. Health is a state of complete physical, mental, and social well-being, not just the absence of disease or infirmity. Wellness is an active process of making choices towards a healthy and fulfilling life, encompassing various dimensions of well-being such as physical, mental, emotional, social, environmental, and spiritual. These terms are interrelated because physical fitness is a component of both health and wellness, and they all contribute to overall well-being and quality of life.
