My comment wasn't intended to put down KOTG or his methods. In fact, I'm very much interested in them and have already incorporated some of his exercises like backwards uphill running and the nordic hamstrings to my workouts. This is thanks to you starting the thread, so much appreciated.
For the record, I'm 6'4'' with long arms. I never was a squat god but did and do DL in a respectable range. I agree that as you get older, you need to adjust your training. Closing in on 40, I do mostly lighter front squats and a lot of Bulgarian split squats these days.
I appreciate it. I am certainly not putting down your methods or squatting or deadlifting. I see great benefits of these lifts.
You said you had long arms, I am assuming you might have long legs relative to your torso height. If so, I would recommend hex bar deadlifting v. straight bar. If your legs are not extremely long v. your torso, then straight bar deadlifting might be just fine for you.
I just want the young guy who is working his tail off in the weight room and seeing little to no results (that was me for 30 years, trying every program on the planet and every variation of every lift imaginable) to try out a new method. I don't know if KOT is better for some/most/all, but I do know it is vastly better for me. And that is due to my extremely long legs and the inability to really get much good out of squatting or deadlifting in the traditional sense.
30 years of hard work in the gym is one thing. It is another when you see little to 0 results, no matter what you try, and then stumble upon something like this. I don't want someone else having to struggle for 30 years, beating their head against the wall, like I did.
