Everytime i try to do deadlifts my lower back starts to hurt a lot. It gets to the point where i cant even walk sometimes but for some reason this doesnt occur with back squats and sometimes it doesnt even occur when i try to RDL or Trap Bar deadlifts. I read that weak abs could lead to lower back pain when deadlifting and mine are pretty weak.
Any thoughts on this? Also i dont think my form is wrong . Ive gotten it checked by numerous of people , including one of the bodybuilders that work at my gym(he just told me to stop deadlifting it doesnt agree with my body)
