No, I don't. I watched some videos by Louie Simmons, very informative. Yet my gym is not suited for any higher sophistication of trainings methods, so I am keeping it rather simple.
I learned about reverse hypers from gymanstic bodies by C. Sommer. I found them quite effective when I could do them few years back. Unfortunately, I am still figuring out where I can do them in my current gym or at the outdoors calisthenics place :D
