The book Back Mechanic completely altered the course of my athletic career, and inherently my life. Mondays are Jiu Jitsu days. Usually, on Monday nights, I would experience crippling post Jiu Jitsu back pain, and often have an incredibly difficult time sleeping. This pain would persist through Wednesday, which is another Jiu Jitsu day, thus leading to Thursday being even more horribly unbearable than Tuesday was. If I needed to do yard work on Saturday, I’d have shooting nerve pain down my leg on Sunday… which is another Jiu Jitsu day, that I would never be healthy enough to attend. The pain is gone. I have reclaimed my training. I’m doing crazier stuff now in BJJ than I’ve ever done.
