However, since we're in the 'you don't know what you don't know' thread, I really have to ask. Are Jeff's training exercises really that good?
I can tell you for sure that the exercises I linked are great and essential. I have found them on my own over years, and it was a breath of fresh air to see someone present them.
On the other hand, a topic that interested me for a while was rate of protein absorbtion (i.e. "Can we only absorb 16 grams of protein in a sitting, and eating anything over that is a waste."). Jeff presents a strong opinion, which is that there is no limit, but I don't think his logic is solid. Seems like the issue is still very much under debate, and while what he says makes sense, I doubt he knows it to be fact, though he presents it as such.
On the other hand, I do buy into the whole "physical therapist" part of his brand. But you can't keep pushing new videos telling people to do the same 5-10 exercises.
