Straight Line

I am swinging the bar in front of me. This is causing me to lose momentum, the bar is farther away from me and it has to travel a farther distance. Tonight I was working on trying to get that bar to travel in a straighter line. I think I may have discovered I am shrugging my shoulders too late. If I start shrugging them about mid-thigh I seem to get the bar moving in straighter path once my ankles, knees and hips finish.
