Weight Training & Conditioning for high schools

I am only a middle school coach, but I have experience with S&C at both the collegiate level and the high school level. I believe that the best way to train a football team, whether it is with a lack of time or not, is with circuits and supersets. This does a number of things, it gets the kids stronger (especially when they're tired, as they will be in a game), increases mental toughness (ability to push through the pain and finish strong), and the ability to get lots of quality work in a smaller amount of time.

Workouts of this nature also provide more time for position specific emphasis during spring ball (with limited contact hours) by allowing guys to get their lifting done, then get their football skills honed. As I said, this is just my opinion and I would also like to hear what others think!
