7. Running every day
This is the trick that most forget to consider. A good runner does not run daily. Running puts a lot of pressure on your lower and upper body. Your body goes through a lot of wear and tear when you run. So proper rest is necessary to revive your health. Take ample rest and keep days off.
8. Ignoring post run activity
Many people think that just running is enough. It is not. Your body has been doing some work. You have to calm it down now. Using as much as a foam roller to do some light stretching could help.
