The Strength Psychology program is all about improving your mental toughness.
What makes this program unique is that it's all about thinking differently. There are no real physical components.
It would be best to watch each video individually and apply what Mike Gillette instructs incrementally.
It's not recommended to watch the entire video series at once and attempt to overhaul your life in one sitting.
To most people watching these videos this is all brand new information with New Perspectives that take time to digest. It's about developing new habits, removing old ones holding you back and creating a new vision for your life!
Use the notes section in the back of the printed book for anything you need to spend extra time on and you can revisit those sections of the videos.
