Hi i did squats with weights in my house and i didnt know the right way. I put the barbell on the bone of my spine instead the shoulder traps. I found out that it is supposed to be your traps not that bone as it could cause spinal injury. Its been about 5 days i can make my back straight properly or walk atraight. I have to bend a bit otherwise if im completely straight it feels like there is no energybleft in my curved back area. It also gives me pain when i completely straighten the back.
