Not sure where to put this, I hope this is alright. Feel free to move it if it isn’t. Anyway, a couple of weeks ago my friend was deadlifting 280 and decided to go for a max set. He got 17 reps. Yesterday he went for a PR at 315 and couldn’t do it. I was shocked that he could pull 280 17 times but couldn’t even do 315 once.
One thing that I have noticed and we are beginning to work on his is difficulty getting the first rep. It is substantially harder for him to get the first rep because of the lack of a stretch reflex. Because of this i have now got him pausing for a couple of seconds at the bottom before lifting every rep. So i guess my question is, why is there such a dramatic drop off as weight is added?
