Question

question 1-12
after finishing using free weights, the next step is to
run for several minutes before moving to the next exercise.
leave all the weights on the floor so that the next person may use them.
alert the instructor to clean up the area.
put all weights back on the racks before moving to the next exercise.

Explanation:

In a gym setting, proper etiquette and safety practices require that after using free weights, one should return them to their designated racks (like weight racks) to keep the area organized, safe, and accessible for others. Running after free weights isn't a standard next step, leaving weights on the floor is unsafe and against gym etiquette, and alerting the instructor to clean up is not the participant's responsibility—they should put weights back themselves.

Answer:

D. put all weights back on the racks before moving to the next exercise.
