When I am hitting my driver should both arms be fully extended straight and stiff? Somone was telling me pulling my right elbow in might help? I am a righty
Your arms should never be stiff. The same rule applies for all clubs.
Set up and relax your right hand, release the club, your hand should swing straight out. If it swings toward you, you are too far away. If it swings away from you, you are too close.
Its a conundrum,and difficult to get right,but you should tuck your arms in so the 'rest' on your chest.Its not easy to do without tension,and needs practice
