Thoughts from The Coach / Author

Richard Diaz

What an incredible journey this has been so far. In over 25 years of clinical assessment and experience based interaction with thousands of athletes, it took up until now to realize the work portrayed in Training The Dark Side.

Getting away from what others believe and have written.  Finally, trusting in my own work and allowing my experience to guide me was an incredible undertaking.  Allowing logic, perception and science from thousands of case studies to meld into an undeniable outcome.  I am confident that those that open their minds and listen to what is revealed here will be an absolute game changer!
