Greeneville's offseason conditioning and weight training program is better than many college football programs, and that is not an exaggeration. If you are on twitter, go check out
@coachcraw4d. He posts a lot of videos of their workouts and conditioning. Look through his past videos and posts, and you will see how they have so many recruits and why they are so dominant. When your QB and WRs are benching 300+, hang cleaning 300+ and squatting 450-500, not many high school teams are going to be able to keep up. Their weight room numbers are insane. Obviously, football is played on the field and not in the weight room, but that is the backbone of their program.
