Answer
Brief Explanations:
To determine which activity meets the goal of a vigorous workout, we analyze each option:
- Sprinting fast around the school track is a high - intensity activity that elevates heart rate and uses large muscle groups vigorously, fitting the definition of a vigorous workout.
- Walking casually with friends to school is a low - intensity, light activity and not vigorous.
- Floating in the pool is a very low - intensity activity, not vigorous.
- Stretching as part of a warm - up is for flexibility and preparation, not a vigorous workout.
Answer:
A. sprinting fast around the school track
