As a fyi re thread (Weightlifting Warm Up Protocol): I switched to "Dave's" jumps and it made a difference for my deadlift. I always thought you "had" to do warmups and slowwwwllyyyy get to your 1RM. This method allows me to well as he/you said take them more seriously. Generally before 80-90% my mind is jumping - as it's so lightening quick, you keep the focus.
I used to go from 60,70,80,90,100,110,120 etc every 10 to 200. Yesterday I went; 60,100,140,180,200 aanndddd got 210
So I have very great trust in your feedback.
