John Berardi, PhD, CSCS, Precision Nutrition
I would like to thank you, James and your peers, for putting together THE best web site on exercise, lifting, and nutrition on the Internet. I am thoroughly impressed and absolutely love your website. I teach Physical Education for health and fitness in So Cal, both lecture and group exercises courses, and I recommend your web site to my students every single semester. I feel your web site offers not only factual information, but a philosophy of training I certainly live and teach by. I especially like that peer reviewed references are used as support for all the information offered. I value any kind of source that uses science to support their information, and offer information not only about advanced training, but also on general health without making sensationalized anecdotal claims about progress. Your web site is to notch! Thank you for taking a leadership role in our field of study, and spreading the word of good health to all on the Internet.
Henry L Perry, Instructor Physical Education & Health, West Los Angeles College
We refer to your website quite a bit in several of our classes. Thanks for keeping the website simple and easy to use, yet factual (and not gimmicky!).

Love your site. I use it in my exercise testing the Rx class at Chico State. Keep up the good work!
Scott Roberts, Ph.D., FACSM, Associate Professor of Exercise Physiology, CSU (Chico, CA)
...I am using some of your terrific stuff from your site for educational purposes for my health education and weight training classes...I will be using the photos and exercises for example as a reference tool for my weight training class. I personally lift and have gained 18 pounds in the past year alone from upper body weight training and increasing my caloric intake...is your site paid for or do you accept donations?

I just want to congratulate you and your collaborators for the magnificent and superb homepage exrx. It is for sure the best on the entire www.
Jose Gonzales, DDS, MDS, University of Giessen
I am a Human Anatomy professor in South Carolina and I teach predominantly pre-med and nursing students. I really enjoy your website. It contains some of the most accurate and interesting information on the skeletal muscles and their actions. Your links between the pictures of the muscle locations and their actions is extremely helpful. I use it in my class to demonstrate not only where the muscles are located but to show them the videos of these muscles in use. The students love it and it helps them understand class material much better. Plus they see how these muscles are used in everyday activities.
Tamatha Barbeau, Ph.D., Department of Biology, Francis Marion University (South Carolina)
Your weight training website is really great. I like that the anatomy charts are linked to the animated clips, and will be sure to refer it to my students. I really do like your Exchange List form, since I haven't seen anything like it on the web.
Kathy K. Grunewald, Ph.D., Professor of Foods & Nutrition, Kansas State University
What a terrific website! Easy to navigate, and full of competent information. Thank you so much to all involved. I have been directing patients and class attendees to the site for a couple of years now.

Please continue your work as it is valued by every patient, athlete and consumer of fitness.
Daniel S. Shook, Ph.D., Exercise Physiologist, Cardiac Rehabilitation Program, Westar Medical Center (Westerville, Ohio )
I love your site and always have. All of my fitness testing calculations are done on exrx.net. I don't know what I would do if you didn't offer it anymore. I can't remember how I got by without it... Thanks again!
Moreland Charles, Wellness/Fitness Associate, Federal Occupational Health (Fort Worth, TX)
I am a physician and long-time fitness buff who ran into your website while trying to find references for exercise prescription to assist my patients with their weight loss goals. In a word your site is --TOTALLY AWESOME! The calculators are great! I was able to find 2 reference books on OA and DM exercise prescription that I can't wait to receive. You have done a remarkable job in organizing all the information available. I am so happy to have found it and I look forward to visiting again in the future.
Phylecya Cheatham, MD
I wanted to send along my compliments to your well done web site. I stumbled on it by accident while looking to refresh my memory of some training techniques for my own fitness. I'm a 1993 exercise science grad from UMKC who has moved on to a different career with the American Academy of Family Physicians in Leawood, KS shortly after graduation. Although I'm not active in the field, I really appreciate when I see people who really bring "professional" to exercise science and wellness. So many of us move on to other things due to limited opportunities or pay. Way to hang in there and create such a user friendly resource. I'm also glad to learn of your close affinity to a family physician. I've passed along your link to the Wellness subcommittee chair in our office. Take care!
Jay Fetter, Student Interest Manager, American Academy of Family Physicians (Overland Park, KS)
James, you have a great site. Great, reliable information. I refer many members to your site via our local fitness training manual.
John Mikula, MA, CTRS, CSCS, HFS, TRX; US Department of Defense, Exercise Physiologist, 94 FSS/FSVR (Dobbins ARB, GA)
I am a retired Marine Corps officer and I have been directly involved in training Marines, coaching, personal training for over 40 years. I am currently a professor for an international fitness organization. I recently discovered your web site while using a search engine. All I can say is WOW!! What a magnificent resource for the fitness professional searching for information based on science, I will strongly encourage all my students to take advantage of your well organized, informative, honest and practical web site. Thanks to all your contributors for a superb "Job Well Done"
JK Taylor, LtCol, USMC (Ret)
Hi James, I don't know if you remember me, but I am also a graduate of KSU from back in 1993. I was finishing up my MS and was a GTA in the human performance lab under the direction of the infamous Karl Rinehardt. We didn't cross paths too much, but I do remember you. I am glad to see you have done so well for yourself and have developed such an awesome website. It will be very useful for the work we do here at the Army War College. Keep up the good work!
Melanie T. Richardson, MS, HFI, Exercise Physiologist, The Army Physical Fitness Research Institute, US Army War College
Your web site is awesome. I got on the web a few minutes ago to search for a site to help me learn more about "body workouts." Did I tell you a FEW minutes ago? That's right, your web site is all I needed to see. I know that the information you have provided will help me begin my task in learning how to maintain my body. I have even sent this to myself at work, just so I can forward this to my coworkers.
MP RIOS, US Marine of 20 years
I recently started taking exercising and eating seriously. Your site is the best I have found for explaining everything. Please keep up the great work.
Brian Leach, US Air Force (Ramstein AB GE)
I just wanted to thank you all for a wonderful web site. I have been using your guides and tips for the past 2 years and it has honestly changed my life. Your site is incredibly detailed and there are no catches to it. Thanks again and keep up the good work.
Abdulkadir Sahin, Coast Guard Recruiting Command (Arlington, VA)
I am a Soldier currently serving my second deployment in Iraq. I have been doing weight training and running on my own with tidbits of advice here and there, but have been in need of further instruction. Your site provided what I need and then some. I have recently suggested your site to other soldiers. Again, thanks.
SSG Jason Sperling, Kansas Army National Guard
I am extremely impressed with your website. The detail to the exercises and the completeness of the whole package as a guide that can be cross referenced so quickly is outstanding. I can truly use the information contained on these pages to train myself as well as the soldiers in my command. Thank you for your outstanding efforts. It also helps that most of you are "Wildcats!"
James Mahurin, SGT, US Army, Infantry
Just wanted to take this opportunity to say thanks for creating such a great resource for health and fitness professionals. I have used your website and referred it to so many people over the years. I am currently the head strength and conditioning coach for Idaho State University Athletics. I work with 14 division 1 teams that consist of over 300 athletes. I have been coaching and personal training for over 25 years. I also have 10 national certifications, but have never come across better information than ExRx.net. I love telling athletes and coaches about your site and using it as a credible resource.
Mark Campbell CSCS, ACE, AFAA, ACSM, YMCAFS, Head Strength and Conditioning Coach for Idaho State University Athletics
Hi, have loved your site for many years....noticed that you had used me as one of the references for the 1RM calculator. Thanks and keep up the great work!
Robert dos Remedios, Head Strength and Conditioning Coach, College of the Canyons, 2007 NSCA Collegiate Strength Coach of the Year (Santa Clarita, CA)
Great job putting together a comprehensive site full of all the ingredients needed to educate the strength/fitness professional and help everyone design and implement strength programs. I have been in the field of strength and conditioning for 13 years and am pleased to see someone presenting the basics (in detail) without bias for any one training system. Well done. Excellent detail in all areas ..structural kinesiology, nutrition, exercises, classifications, etc. There are thousands PhD's and more theorists and researchers out there to draw information from; but the game of figuring out what's true science vs what's practical, prudent, effective, and efficient leaves much to be desired. You're efforts and approach is appreciated. A great teaching tool for students and professionals alike.
Al Jean, Head Strength & Conditioning Coach, Coastal Carolina University
I have been going over you web site and think that it is great.
Robert Stelma, A.T.,C., C.S.C.S., Supervisor- Athletic Training Services, Geisigner Wyoming Valley-Human Motion Institute (Wilkes-Barre, PA)
Incredible Site: I must say that as a professional athlete who tries to stay as informed possible, this site is simply unmatched in the quality and scope of content. A personal trainer is incredible, but no one knows your body like yourself and this site has such a vast array of knowledge from instruction, to myth, to helping one understand what is going physiologically during training, it has helped me modify and adjust to reach an optimal level of preparation and performance. Thanks.
Austin Coose, Baseball Pitcher for the Tampa Bay Devil Rays (Tampa, Florida)
I just had to thank you for the time and effort you have put into your website. It is truly the best. I have been using it for my athletes to refer to for clarification on different exercises, anatomy and nutrition. Keep up the good work and I look forward to your updates.
Bruce Marshall CAT(C), Head Athletic Therapist, Carleton University (Ottawa, Canada)
I have found your web site to be an amazing tool and great guidance for my team in efforts to improve their fitness and level of competition.

Congratulations on your superb website. The quality and quantity of information is truly remarkable. Thank you for exhibiting one of my books and we would be pleased to link it to our YMCA website. Thanks again for your excellent work.
Dr. Wayne Westcott, Ph.D., Fitness Research Director, South Shore YMCA
First off, your site is a terrific resource for any exercise professional. I was first introduced to its existence while studying Exercise Science at Southern Illinois University Carbondale. I have since taken a job where I oversee our YMCA programs, wellness center, and personal trainers. I love the site and use it constantly. I refer all of my trainers to this site to add variety to their workouts and to stay on top of the always evolving field of exercise science. Thanks and keep up the good work.
Chris Turner, BS, CPT, Program Director, Danville Family YMCA (Danville, IL)
Hi. My name is Micah Barcalow, and I am an Assistant Program Director at the Jorgensen Family YMCA in Fort Wayne, IN. I am responsible for the day-to-day operations of our fitness center, including staffing. While I hold a degree in exercise and am certified as a personal trainer, I often receive very specific exercise-related questions that require some research on my part. I can always count on your site to provide excellent, unbiased information. I regularly refer staff and clients to your site. I check your site for updates on a regular basis as well, since it helps me keep up to date and enables me to maintain variety in my own personal workouts. Thanks for building a great site.
Micah Barcalow, Assistant Program Director, Jorgensen Family YMCA (Fort Wayne, IN)
I just wanted to say thank you for making such a wealth of valuable information so easily accessible. For health professionals such as myself, it is a valuable tool to use and to recommend to our members.
Dave Ray, Healthy Lifestyles Director, East Valley Family YMCA (N. Hollywood, CA )
Hey, fabulous site! You've really done and excellent job; I'll be pleased to send people over! Dave Drapers review of ExRx: Here's a link to keep handy, like, forever. Next time you don't know how to do an exercise or can't figure out what muscle you're working, drop on by ExRx for a painless answer.
Laree & Dave Draper, Mr. America, Mr. Universe, Mr. World
I want to thank you for such a functional (and free site). I am working with my 60 year old uncle and I was going to use the NSCA materials - but I found your site to be much more user friendly and convenient. I am going to get him started on free weights and with good instruction I think he will enjoy it and stick with it. I am a sales rep with StairMaster (11years) in Florida. I have a BS in Ex phys from Wis. -Madison and MS from UAB - but most of my emphasis has been on CV rehab and aerobic training. Please let me know if you recommend any other materials for strength training beginning seniors. I know Wayne Wescott and am familiar with his materials. Anything else you recommend or do you have any instructional videos? Thanks again for such an impressive and generous site. Please let me know if I can ever be of any assistance to you in return.
Jerry Napp, MS, BS, StairMaster (Florida)
What a great and informative site!
David Ponsonby, Former Nautilus Researcher
