That is a huge part of executing at heavier percentages and being more consistent in the lifts. If your pull is vertical, it's very predictable. The bar will stay close to your body and you will meet it well! If you lean back it can get very unpredictable. We say to finish your extension with your shoulders just slightly covering the bar. "Stay Over the Bar" is the que we use. Also it is important to be really tight and hold position as you initiate your lift. You want to put tension into the bar before you start. Practice lifting from 1 from the ground and then as it gets heavier apply the same pressure, but leave the bar on the floor. This should take care of everything! Good luck!
You're the man bro!
