I've been lifting for about 3 months and I've been sticking with 3x12 for my exercises just to keep it simple because if I overcomplicate it I'll burn myself out. But I've plateaued on my deadlifts because I can barely reach 8 reps before I'm just physically exhausted and I don't want to carry on for fear of bad form and increasing risk of injury.

Is this normal considering how new I am or should I adopt a smaller rep range?
