There are some very good You Tube videos out there on how to do the BB throw. You have to mimic a catapult action when you throw, whereas (if you're right handed) the left shoulder swings down 45 degrees, and the right arm swings up at 45 degrees during release. The torque and rotation of the body generates the force needed to achieve a decent distance. Practice, practice, practice. My DD watched videos and we would practice, make tweaks, and try again. With practice you will be amazed at how much distance you can gain. My DD gained 16 ft in about a week, all by good technique.
