yankeedawg1, while I don't claim to know a lot about the "new way" to become totally conditioned and play hard in the fourth quarter, I remember this. . . .
In the weight room you will build a lot of muscle lifting. Strength is not only necessary, it is imperative. If you take a young man doing 20 reps of anything he will get stronger. If you take that same young man and introduce cardio into his workout, at some point the 20 reps move up to 25 reps. Along with that this young fellow has increased his cardio and can not only knock you on your butt, he can chase and catch you in the fourth quarter. I am sure that there are those on this site that could go into more detail.
One move I would like to see all of these young men have to make, under the guidance of a professional is a serious yoga class. Seems over the past few years we have had some serious muscle pulls. If I were the person in charge of the S&C, my first hire would be someone with a serious yoga background.
Back in the day, most of our high schools were not lifting weights, did not have a weight room. School let out, we went to the field house and dressed for practice. First thing we did was stretch and then do our jumping jacks, push ups and other things that were supposed to keep us on top of our game. At the end of practice and scrimmage, it was wind sprints then laps. Best I remember, we could play four quarters of football, and for some of us that was two way football.
Strength does not catch that running back that is high tailing down the sideline. Cardio and flexability come into play at that point. Too much emphasis on strength in my opinion. Strength training has also laid the ground work for steroids, yes that happens in high school.
Thanks for the Cup of Joe this fine Friday morning and putting up with one old farts opinion.
