This lift obligates the hamstrings to progress. I learned it from Louie Simmons. Contrast that against some textbook techniques which DETRAINED hamstrings.
My 2nd cert was NASM CPT in 2004. I liked their ideas about muscle imbalance/postural distortion. But the stabilization protocols, which I did to correct hip pain, lost me a lot of calf and hamstring size/strength AND did nothing for my pain. Beforehand, I could rep single leg Nordic ham curls. Afterward, I couldn’t with both legs. The pain remained.
No one has THE truth. When I completed NASM PES and CES and Precision Nutrition and RKC, etc., I found value but also vital missing details. Then you listen to Louie for 2 mins and find a golden variant which can only be performed in a way to accomplish the end goal.
Once upon a time, I too liked the idea that there would be organizations which we could all look to as unfailing and unquestionable gods. But as you dig deep, or simply exit childhood, you find that former scientific "fact" gets overturned. As much as I too dismiss a lot of "bro science," I have to temper that against the repeated fact that professional research organizations have done complete revisions of long-held recommendations lots of times as well.
We are all just learning. Be practical. Don't cast your entire lot in with even an established authority, so much as take a piece of their input. If it works, it works. If it doesn't, scrap it, no matter how "right" it should be. It doesn't work for you. Therefore, as far as you are concerned, it doesn't work. Don't care how authoritative the recommendation was. Just be pragmatic.
