Kinda the same but different
i know buddy posted something similar to this but u guys like posting so dont be bitching LOL! anyway i have been doing squats and i notice that my lower back does not hurt but gets really stiff and most of the time now when it gets stiff i bend over and it sounds like water is moving in my lower back and you hear two cracks! how big of a prob is this?
Try switching to leg presses
I may not have Tom Platz legs but I have made really good progress using the leg press. It takes much of the pressure off of your back. You must listen to your body, if it hurts make adjustments and if it continues, don't hesitate to see a doctor before it is too late.
