<human>:  How much exercise should someone do every day to stay in shape?
<bot>: It is recommended that most adults should get at least 150 minutes of moderate-intensity aerobic physical activity, such as brisk walking, or 75 minutes of vigorous-intensity aerobic physical activity, such as jogging or running, per week. Additionally, adults should also do muscle-strengthening activities, such as lifting weights, at least two days per week. However, the amount of exercise that an individual should do every day to stay in shape will depend on their physical fitness level and age.
