Running is a very important exercise in the Marine Corps and takes a lot of practice to master. Becoming a good runner is something that anyone can do with proper training. A few tips are outlined below.
Start out slowly
Don’t overdo it at the beginning! If you’re a beginner, only do what you feel comfortable doing and build on that.
Relax your upper body
Many people run with their fists clinched and their arms stiff. Your arms and hands should be limp as you run so that you are not using much needed oxygenated blood.
You should take deep breaths as you run in order to get as much oxygen as possible into your blood. It is also helpful to establish a rhythm with your inhale and exhale.
Make sure your feet hit the ground properly
You should always land on the heel of your foot and then roll through and push off with your toes.
