Testimonials for Essentials of Elite Performance
Still Wondering if This is For You?
"Dr. Cobb has introduced a different approach to training, one that has been overlooked by the majority of the supposed experts in the fitness field. His knowledge of how the body actually works is astounding. His ability to teach in a manner that takes something as complex as our body and take it to optimal performance, with simple movements, is amazing. In the past 2 ½ years I've only attended Dragon Door workshops (6). Dragon Door has always in my opinion offered cutting edge quality in every workshop. I apply 100% of the material in my business after every workshop, which I think is pretty incredible."— Diane Salettel, RKC II Bedford, OH
"Absolutely fantastic! I learned a lot about myself and why I am who I am and how I am who I am. A lot of my life physically, mentally, emotionally, neurologically, medically and experientially makes much more sense."—Matt Deane, Fitness Professional; Naples, FL
"Excellent program with total integration of how vision, vestibular, proprioception and joint mobility affect the way we move and perform. Excellent program that will strongly influence the way I train myself and others in the future and help with injury prevention and improve function."—Dr. Ricardo Nieves, RKC II, CK-FMS, Carlsbad, NM
"The best student/teacher ratio I have ever experienced at a workshop put this experience as the best fitness industry workshop I have attended. This component was the key to why I learned so much. Attention was given to all the attendees, and plenty of it."—John Rock, RKC II, Personal Trainer; Arden Hills, MN
"This is the absolute best investment I have ever made. This has opened my mind to a new level of training. To be a trainer without this knowledge severely limits that trainer's ability to be effective. I have always been asked to train other people, but I have been hesitant to do so. I knew the knowledge I previously held was not sufficient to be ethical and effective, therefore I rarely trained others Not anymore!"—Lucas Guili, St. Louis Park, MN
"It was as though someone suddenly switched the lights on as to why I have certain training weaknesses and injuries and how I can correct almost all of them instantly."—Martin Brown, Kent, United Kingdom
"This is the most I have ever learned in the time given! Dr. Cobb is THE MAN! Thank you All. Top quality. I feel the same as I did with the RKC and even my NPTT."—James Mortimer, RKC, Personal Trainer; Forest Lake, MN
"I have heard first-hand testimonials about life changing experiences and realized a difference can be made in the quality of life of individuals whom most people have given up on. I am also excited to increase my own chances for athletic success and longevity. Mind blowing stuff. I was particularly impressed by how the system can take almost anyone from currently un-athletic six year old to stroke victims – and make them happier and healthier. I would equate this workshop with the RKC and FMS courses I have taken, which are all far better than most other courses I've taken."—Michael Golden, RKC, Martial Arts Instructor; Rocky Hill, CT
"Z-Health was an incredible experience that left me wanting to understand more, to learn more and to do more, not only for myself, but for my clients, family and friends. A huge amount of information was presented by Dr. Cobb, but done is such a natural and understandable progression that it was like stacking building blocks – he gave us the base upon which to build freedom of movement."— Andrea Chang, Seattle, WA
"I have done a number of workshops working for a Neurology Clinic in rehab for 6 years and by far this is the most applicable system I have seen and been taught. It relates every aspect of the human body. The quality of the materials very specific and the instructor. Dr. Cobb and all of his staff were great."—Sandra McClellan, Fridley, MN
"Z-Health has made me a stronger and healthier athlete. I'm excited to continue my training and help others have the same experience. Dr. Eric Cobb has a talent being able to teach and be personable at all times. Dr. Cobb and his instructors were all very willing and very knowledgeable at giving explaining any Z-Health question asked."—Kristine Gill, RKC, EMT, Firefighter, Seattle, WA




Z-Health is cutting edge material that will give additional ways to treat patients or train clients. The techniques can work fast, but it is a process that you can use professionally and personally for a lifetime.
Tom, Iowa
I cannot tell you how much I recommend the Z Health certifications. After attending the Essentials of Elite Performance, I’m dedicating 10% of all brain function to finding a way to fund my next 2 years of getting through all the certification levels, ha! I’m a very critical person, and I have high expectations (that are seldom met by continuing education classes), and Z-Health is jaw dropping, hands-down, 100% amazing.
Shanie, San Francisco
Just try it, the Essentials of Elite Performance course is the one of the best athletic improvement courses and the most paradigm shifting course you can take for the cost. You will be amazed with the results.
Mike, New Jersey
You could not use your money in a better way. It is an investment in how you are going to live your life for the rest of your life if you want the best for yourself.
Bente, Denmark
The workshop was inspiring; it gives a fun, intellectually stimulating and satisfying approach to the human body and movement. It challenges a lot of ingrained beliefs and forces one to rethink the approach to training and teaching.
Erik, Denmark
Do it. It’s absolutely the best investment I have made in my career and life. Your whole world will expand and improve at the end of every workshop. There is nothing else out there like it that I have found.
Leslie, Los Angeles
Do you want to be a part of the future of the fitness industry? Gotta go to “Z”.
Stephen, Oklahoma
I needed CEUs for my NASM re-cert, but I was very excited about this workshop after having been bored by many others before it. Now it is more than a CEU quest; it has changed my view of training profoundly. I look forward to continuing [my] education and certification with you! The best workshop I have ever taken – REALLY!
Karen, Maryland
I 100% recommend Z-Health to anyone who is serious about becoming the best professional they can be.
Thomas, New Jersey
All of life is discovery. Why not discover how movement can improve everything you do physically?
Gary, Colorado
I think you guys are awesome. Passionate, articulate instruction and ample opportunities to get feedback on my performance and teaching made this a great experience.
Mark, New Mexico
I would highly recommend Z-Health. It will change your view of what you do, no matter what you do. Don’t hesitate.
Henri, New Hampshire
Awesome! I like the fact that you guys are able to present on such complex topics and still manage to do so in a language that everybody can understand. Extremely good content and good balance between theory and practice.
Tommy, Denmark
I move better; I feel better; I find movement fun again. It’s like the thrill of being a kid again. Movement becomes a thrill and a joy. If we are interested and willing, we can get better with age and good training. Z-Health is essential for good training.
Ron, California
The rabbit hole goes much deeper. Z-Health is much more than a joint mobility system.
Michael, Illinois
If I get one idea [from a workshop] and implement it, it’s worth it. This workshop gave me hundreds of ideas and I want to implement them all. I’ve absolutely never had more value for money and I’ve done a lot of workshops.
Rob, Netherlands
If you want to truly get out of pain and improve every function in your body (including the problems you aren’t aware of) then this course is priceless. You can’t buy a perfectly functioning body.
Jenny, Edinburgh
"Suffice it to say that if not for Z-Health, I would have given up on the idea of living a life free of pain and one of happiness. "
