Getting lower back pain when performing the dead lift isn't that uncommon--especially if the exercise is performed improperly, too many sets, too heavy of weight, etc, and some genetic physical abnormalities.another weird thing is that i had the same weird feeling a month ago when i tried deadlifts for the first time. (i just assumed i did them wrong and never tried them again) Am I messing something up or can it just be that my lower back is weak?
What type of dead lift are you doing, and how was this performed? How many sets, and what is the frequency/volume of the other portion of your training? How often per week, and how much rest is given between your workouts?
What is your goal/purpose of training? And, lastly what is your nutrition/diet look like?
