The phrase "enough exercise" means engaging in physical activity to a level that is considered beneficial for one's health and well-being. It refers to the amount or intensity of movement needed to improve cardiovascular endurance, strengthen muscles, increase flexibility, and maintain a healthy weight. The specific amount of exercise required varies depending on factors such as age, fitness level, and individual goals. Generally speaking, adults are advised to engage in at least 150 minutes of moderate-intensity aerobic activity or 75 minutes of vigorous-intensity aerobic activity per week, along with muscle-strengthening activities on two or more days a week. However, any physical activity is better than none and even small amounts can provide health benefits.
