What People Are Saying About JrFit™
The obesity statistics depicting our nation’s youth is staggering. The fitness industry is now being called upon to provide information and programming for this very important population. JrFit examines the specific needs of children regarding exercise, and what it takes to create and teach kid’s fitness programs. I highly recommend the JrFit program, I have been leading and developing children’s fitness programs for fifteen years and the American Academy of Health and Fitness has orchestrated the perfect specialty certificate to support your success in youth fitness.

JrFit is an excellent, comprehensive program that addresses youth fitness and nutrition. This program helped me start a youth fitness program for kids both wanting to try-out for sports or just learn about being active. I also found that parents and families enjoy the nutrition programs, as they help the entire family live healthier. The books are irreplaceable resources for Athletic Training students looking for more creative ways to address youth fitness and conditioning to ready the return injured athletes.

The JrFit course is an excellent choice for today’s fitness professional looking to work with youth. The program is comprehensive and will prepare anyone looking to make a positive impact in youth fitness or more advanced athletic preparation. I will recommend this course as an essential piece to learning the ins and outs of training youth and adolescents.

JrFit provides the fitness professional (personal trainers, coaches, athletic trainers) with the information necessary to design sound conditioning programs for both the young athlete and growing adolescent. It dispels the myths and fears associated with youth strength training and offers research based recommendations for strength training and sports skill development, coupled with sound nutritional advice the entire family can benefit from.

JrFit IS the definitive course for fitness professionals desiring a science based, comprehensive approach to training today’s youth. I highly recommend JrFit. Tammy Petersen has done a great job creating a valuable course that fills a gap in our industry. JrFit was an excellent tool for expanding my current knowledge and training ability. I found the course to be properly organized, the information was scientifically sound, and the textbooks were authoritative for this specialty.

JrFit™ provides an outstanding collection of resources for fitness professionals interested in improving the health, fitness, and athletic performance of youth and adolescent populations. Programming to address the epidemic of childhood obesity has been among the top three industry trends, as identified by the ACSM’s Worldwide Fitness Trends Survey, every year from 2007 to 2010. Fitness professionals completing the JrFit™ program will be well-equipped with the knowledge and skills necessary to safely and effectively meet the demands of this rapidly-growing population of young exercisers.

JrFit is exactly what I was looking for! The course materials are structured and organized in a professional way, providing easy study and absorption of the content! The information within the program is presented in a comprehensive, yet practical (information is detailed, but easy to understand – not written in a highly scientific or technically complex format) way that has allowed me to be able to immediately apply the knowledge and skills necessary to safely and effectively train children for fitness and/or athletic sports conditioning. In the JrFit program, it is easy to distinguish between the information related to general fitness training and athletic sports conditioning for kids. This is important because not all kids have the desire to train athletically, but all children should be involved in training that will benefit their overall health and wellness. The structure of this program provides a progressive learning path that will develop highly skilled and proficient trainers who will have the potential to save our youth from the negative effects of inactivity and obesity. Thank you for creating such a high quality program!

The JrFit Program has all the detailed information you’ll need to create comprehensive and customized fitness and sports conditioning programs for children and adolescents alike. The nutritional component is also very informative. There’s nothing else out there that comes close to this wealth of information and ideas.

I am confident that, like me, you will find JrFit an excellent resource for training children of all ages and fitness levels.
