Physical strength refers to the ability of a person to exert force on physical objects. It is often measured by how much weight a person can lift or how much resistance they can overcome. Factors that contribute to physical strength include muscle mass, endurance, and overall fitness level. Training and exercise, such as weightlifting or bodyweight exercises, can enhance physical strength. Nutrition also plays a crucial role, as a balanced diet provides the necessary energy and nutrients for muscle growth and recovery. Regular physical activity helps maintain and improve strength over time.
