#TytaniumTip of the day: Joint Stacking - (not a method for organizing ur marijuanas) This is the idea that you should maintain vertical alignment between your bar, wrist, and elbow during any pressing movement. At any point in your range of motion, you should be able to draw a perfectly vertical line connecting the three points. Why? Go grab a water bottle. Set it on a flat surface. Notice how it stays upright without any help. Now lean that bottle over 20 degrees and let go. It probably rotated at it's base and fell over. The same tendency exists in a pressing movement. Keep the weight over the axis of rotation, and your forearm will act like a column, supporting the weight with no added effort. Let that weight drift, and now your forearm is a lever, allowing that weight to apply an additional and unnecessary rotational force to your elbow/shoulder. Without proper joint stacking, you now have to produce enough force to prevent the weight from falling over AND to press it up. That's just silly.
