What do you need to do to meet the Physical Activity Guidelines for Americans? What are the benefits if you do? What are the consequences if you don't?

What will be an ideal response?


Ans: Compare your current level of activity with the national guidelines. Being more physically active increases muscle strength, balance and endurance, support physical and mental health, improves cognitive function, helps manage weight and combat weight gain, reduces blood cholesterol and bp, and helps prevent the onset or progression of several chronic diseases. Sedentary lifestyle results in the loss of these benefits.
