C
The combination of aerobic and bone- and muscle-strengthening physical activities leads to health benefits for people of all ethnic groups and ages. Physical activity is safe for almost everyone, and the health benefits of physical activity far outweigh the risks. Additional health benefits are provided by increasing to 300 minutes a week of moderate-intensity aerobic physical activity, or 150 minutes a week of vigorous-intensity physical activity, or an equivalent combination of both. For all individuals, some activity is better than none.
