Here's a great article on the reasons why one should be cautious with
"testimonial evidence."

Some of this sound familiar? Go to any strength forum, especially grip related and you'll find individuals who have been involved in grip work for several months and "Presto"! They are
all the sudden experts in the field.
Lastly, before dumping your hard earned money into someone's instructional e-book, verify if there's any evidence to support what they are selling besides testimonies from others. Look for some science behind their proposed training concept(s). Find out if their ideas go against known physiological facts, biology, physics, body mechanics, etc. Do some basic research before buying.
Nothing wrong with listening to others viewpoints but ask questions to yourself and the one selling the product.
Enjoy!
Stay informed and stay Strong!!!
