Part 9: A discussion on diving and air consumption: Arm movement


If you’ve ever done an aerobics class, there’s a reason the instructor makes you do all those arm movements until you feel that they are going to drop off. It’s exactly the same reasoning that made your diving instructor want to tie you arms to your side during your first dive course.

The introduction of upper body movement can increase your metabolism by up to 30%. Great if you want to burn calories in an aerobics class, disastrous for air consumption on a dive – enough said!
