D) all of the above
All of these are barriers to physical activity
It helps your health in many ways but one of the greater aspects, is it allows your blood to flow faster making your heart not have to a work as much. Your resting heart rate can help you determine how fit you are. If you have a low resting heart rate it means you are healthier, and your heart is more powerful. Because it doesn’t need to pump as many times to get your blood flowing
I just had a big test on marijuana, steroids and inhalants
One of the reasons a teen would choose not to do marijuana is because it can cause you to have short term memory lose. It can also cause you to loose you’re coordination. It also can cause some one to have lung problems.
Hope this helps you have a great day!!
Good luck
