IMHO, they lead to a long term mindset that is defeatist.
Please explain this. I understand how accepting slower progress than otherwise possible could be seen as defeatist. But how is approaching anything in the iron game from a long term perspective defeatist? It seems like longevity is a key component of accomplishing anything significant fitness wise. Can't squat from a hospital bed or an early grave.
I agree with that entire line of thought, except small jumps have just not worked well at all for me. If I can only add 2x2.5s then I am it ready to jump and I just do more sets where I am at. In my work sets I jump at least 20 lbs in the squat and dL and 10 in the bench, generally more. This is not kamakzi make it or die, it is keep adding volume leaving reps in the tank. If my bar weight slows down or I start to grind I drop the bar weight next set. In fact I often do a workout I call “ fun with quarters” in the squat or dL. I pick a weight, say 405 and do a set. Then I add 2x25s. I do another set. Then I take off the quarters and do another set at 405. I generally try for three of these couplets. Actually have done it in bench too. You might think the lower weight is too light. Nope, it is a great speedset.
And the confidence and body feedback practice I get is very good for lifting bigger weights. Or pushing up my barweight on set of 3, 5, or 7. Because I do no singles anymore except speed DLs.
Other ways to do it? Sure
Just in my experience this way works better.
