The Law Of Correspondence states that your outer world corresponds to your inner world. What this means, is if you think of yourself as a overweight person with no self-discipline, this will automatically be your reality.
So in order to change your outer world you have to change your inner world FIRST. No matter what you do, you will always look like you do in your head.
By imagine the person you want to be, you will automatically become that person.
So before you go to bed, imagine yourself as a healthy successful person and guess what, you are going to see the changes in your outer world. Give this practice at least one month an you are going to see changes.
This not only works in fitness, but in your personal life too. Do you want more money? Imagine yourself with the desired amount of money you would want, and it will manifest itself in your outer word.
Sounds to good to be true? Maybe to easy?
The law of correspondence is a universal law that works for everyone. It is the same as the law of gravity, it is the same for everyone and you cant work against it.
Make the change in your head on your outer world will automatically adapt. Good Luck!
