I've been a trainer for 10+ years and really appreciate RAD's approach to providing solid research, education, and techniques I can easily use when designing programs for my clients. They take an approach that is easy to follow, understand, and begin integrating immediately. Then the tools...wow. The design was obviously well thought out and it becomes quite clear that these are no ordinary tools like tennis or lacrosse balls. They were designed for this stuff. In my opinion, this bundle is a no-brainer for anyone interested in learning more about human movement principles, mobility drills, flows, and wanting to use really effective tools.
