Use the forearms to provide power.  Most golfers do not think of using the forearms.  Most golfers use the arms to try to hit or lift the ball but they do not know how to use the arms to create power efficiently.  The efficient movement of the forearms are engaged when Ben Hogan describes the motion of the arms in the down swing to be similar to the motion of throwing a medicine ball at a target on the wall.  Executing this throw efficiently uses the forearms.  The feeling in the arms in throwing the ball is the feeling of a stretch and snap in both forearms

In the golf swing, energy is stored in the forearms during the back swing and energy is released in the down swing.  The power generated by the forearms is why long drivers have well developed forearms that are used efficiently during the swing to snap the club head toward the target.

During the back swing, when the corner left upper arm stretches up, feel the bottom of the left forearm stretch to the right and feel the top of the left forearm resist to the left.  When the corner of the right upper arm stretches up, feel the bottom of the right forearm stretch down.  This builds energy to be released in the down swing.

During the down swing, when the corner of the left upper arm “bounces” up, feel the bottom of the right forearm “bounce” down.  This automatically causes the bottom of the left forearm to snap up to the left.

Using the forearms in this manner provides additional distance to your golf shots.
