This manual is seriously awesome. I'm really interested in anatomy of the human body and how you explained the lower body was really easy to understand and interesting. You answered a lot of questions for me regarding ankle mobility because I would always do various searches on google and T-Nation because I noticed the back of my ankles would be a bit painful with certain movements, and your mobility drills helped me a lot.
Not only that, but I always had a slight pain in my lower right knee (below patella it would seem), and your ankle mobility drills have substantially improved this, and I don't get any pain from doing pistols and such. My hip mobility was always on par thanks to MM, so I guess the ankle mobility was the weak link.
Two quick things I also found interesting:
1), I would always feel a bit tight in my hamstrings after an intense resistance workout, so I would always focus static stretching my hams a bit more. This never seemed to make any difference though. Then after focusing on my hip flexors and doing those first 3 static stretches in your manual, and minimizing my hams stretching, my tightness in the hams is really not a problem anymore.
2), the EQI's are awesome! They are very new to me and the first time I could only hold it for 15 seconds (not a surprise after Waterbury's Full Throttle workout haha), but I think the EQI's have also improved my anterior chain streching and tightness of hams.
