The other day while doing leg presses I experienced a sudden discomfort in lower back lumbar region. The reason this occured is because I brought the weight too low which caused my lumbar to straighten or curve in the the other way. Now that this has happened I feel pain only when I am not in the neutral lumbar position or when I bend my lower back just above the pelvice, lets say to pick something off the floor. What has happened?![]()
