I have had the 3rd edition for almost a year and about two months ago purchased the fourth on Kindle. I think the updated information is worth the extra money and I am glad I purchased this book. I would like to share though that , it is very important that if you are personal training and not just working with Athletes, you get the Essentials of Personal Training, because the extra chapters on Special Populations like clients with MS etc... make it worth it. However, as far as healthy athletes are concerned, this book is an excellent start and will carry you into the intermediate level, whereas the NSCA topic specific books seem to go a little different.
