Does Air Alert cause muscle imbalances like these website say?

No, it does not if the athlete follows the program correctly and does everything that is stated in the DVD. Many athletes that use the program fail to work their hamstrings which is crucial to avoiding muscle imbalances. The program DVD and training booklet specifically states and stresses to work the hamstrings 2 days per week.

Many athletes try to get the program for free on the internet. What they do not realize is that they are not getting the full written and DVD version. They are not getting all of the information. In other words, athletes are doing it incorrectly and not even realizing it. If they do experience muscle imbalance, then it's because they've missed vital information that we send to all athletes in the complete program.
