Question

federal guidelines recommend that children perform a vigorous workout at least three days a week. which activity would meet this goal?
○ sprinting fast around the school track
○ walking casually with friends to school
○ floating in the pool before swimming class
○ stretching as part of an exercise warm - up routine

Sprinting fast around the school track is a vigorous physical activity. Walking casually, floating in the pool (before swimming class - not the swimming itself which would be more active), and stretching (warm - up, not vigorous) are not vigorous workouts.

sprinting fast around the school track
