Crunching sensation in low back when squatting and deadlifting

[Jackedshrimp760]

Is anyone familiar when a crunching/tingle sensation in the low back in the bottom half of the squat and deadlift, it is not particularly painful but really uncomfortable to the point that i feel like i cant lift the weight, normally happens after 2 or three reps. I am not sure but I think it is the sections of the vertebrae grinding on each other due to back hyperextention, should i just focus more on straightening out my back and contracting my abs/butt?

What is your age? Any other symptoms?

26 with no other symptoms, it is likely along the lines of what you mentioned. Probably not surfaces grinding on each other, but probably more like repeated small cavitations within some of the joints. These can occur with loaded movement. I wouldn't necessarily worry about it, but I may pay more attention to your position. At this point, I'm more concerned about you missing a rep because of this sensation than I am the actual pathophysiology of what is occurring.....if that makes sense.
