Physical activity is important for both physical and mental health. It provides energy, improves mood, and adds years to one's life. There are three main types of physical activity - flexibility, aerobic or cardiovascular, and muscle strengthening. Regular exercise educates people on healthy diets and monitoring their heart rates. Group activities can include walking, jogging, and running exercises done in sets with rest periods. Students are tasked with creating and presenting their own exercise routines that incorporate the different types of physical activity.
