physical activity that requires some increase in
breathing and/or heart rate and expends 3.5 to 7 kcalories per minute.
Moderate-intensity physical activity
physical activity that requires a large increase in
breathing and/or heart rate and expends more than 7 kcalories per minute.
Vigorous-intensity physical activity:
allows the joints to move freely, reducing the risk of injury.
Flexibility
supports the ongoing activity of the heart and lungs.
Cardiorespiratory endurance
enable muscles to work harder and longer without fatigue.

and muscle endurance
improves as physical activity supports lean body tissues and reduces excess body fat.
