This isn't going to be a terribly long post, but I just wanted to point out someone who I have been learning more and more about: Robert Dos Remedios, M.A. CSCS. Coach Dos is the head S&C coach at College of the Canyons in Southern California and is a growing name in the S&C community for his slightly different approach to lifting. He does a lot of non-traditional exercises for conditioning in addition to the usual 'jacking iron' that every football S&C coach will do. I could try to explain it more, but frankly I just don't have the background to accurately give detailed info on his stuff. Instead, I'll link you two cool sites that I really enjoy: Dos' Website and Dos' Youtube Channel. Two things to consider from his YouTube stuff: 1-no 'fatties' in his CoC football videos, and 2-how mentally tough do you think his guys are after doing some of his workouts? A lot of coaches pay a lot of lip service to wanting to have tougher athletes, but having done some of Dos' cardio strength workouts, I can tell you that finishing those with max effort takes you to a special place and you're PROUD of yourself when you're done.
You can find a lot of neat products from Coach Dos at his website, including his two books that are both easy reads and have lots of great stuff in them. As an aspiring HC, I think there's absolutely a place in every program for his kind of stuff.
