If you run you know that it can be such a great feeling of freedom and accomplishment to do a run. However there are literally a lot of moving parts, and they all effect each other.
Here is a list things to consider when you go out for that jog.
- Hip movement
- Arm swing
- Speed of pronation
- Foot placement
- Steps per minute
- Vertical displacement
When you get tired think about these things instead of how hard it is.
I found a neat article that gives more detailed descriptions here.
