Adults should participate in muscle-strengthening activities at least twice a week, according to health guidelines. These activities can include weightlifting, resistance training, or exercises that use body weight, such as push-ups or squats. Engaging in these exercises helps maintain muscle mass, improves metabolic rate, and enhances overall strength. Incorporating a variety of movements targeting major muscle groups is also essential for overall fitness. Consistent participation plays a significant role in reducing the risk of age-related muscle loss, promoting longevity, and improving functional independence in daily activities.
