Harsh Truth! How often have you felt inspired and then done nothing about it? Stop looking for the secret. Any article with "secret" in it is playing on your psyche.

Exercise is a never ending process that should aim to continuously nudge the needle towards improvement. Your health is either a priority or it's not.
