at the peak of my deadlift i was doing 405 for 5 reps. i made a rapid increase from 385 to 405 in about a month. a month or so past the workout that i did 405 for 5 reps, i tried doing deadlifts again and it just wasnt happening. matter of fact, i hurt my lower back(not serious), but i was kind of tender down there for about a week. anyway, took a little break from deadlifts and started in again and i am nowhere near the strength i used to be when i was pulling up 405 pounds.
how is it that with continuous training, a lift can decrease so dramatically, assuming that everything else is constant(diet, health in general, etc.).
ive had this problem with other lifts too, but not to the extent that i have with deadlifts. however, after making progress in weight with a particular exercise, i will come back to that exercise a couple weeks later(or even in some cases just a week later) to find that i have decreased in weight(basically gotten weaker).
anyone else experience these periods of "strength regression"? any advice?
