"There are many effective swim styles. But the most effective swim style is that which is based on what each swimmer’s body is physically capable of doing. Target physical limitations and allow stroke mechanics to develop harmoniously with the swimmer’s physical assets."
"John Mullen is a true professional and a clear expert in the field of sports medicine and injury prevention in swimming. His Troubleshooting Manual is clear, concise, and extremely well-presented. It directly addresses critical issues that coaches deal with on a daily basis with their athletes. This manual is the best on the market and will make every coach more adept at understanding swimming physiology, and thus helping our athletes with healthier and longer swimming careers.
Thanks for the great work and all that you do for the world of swimming!"
"I like the approach since there is so much more to developing athletes and if they aren’t tuned the right way and or don’t understand how to manage their environment, then the chances of success are essentially blind luck."
"The Troubleshooting System helps us connect the dots in and out of the water. It is a great product for anyone interested in the human body and swimming."
"An impressive and thorough accumulation of knowledge and thought."
