This video talks about the right arm and how we need to aim to support the golf club with that arm to control our low point, angle of attack, swing path and ensure the body has a range of motion available to control and power the golf ball. If we alter the right arm from address to impact by a large margin then timing becomes complicated as the clubface turns over and the body has to alter it's form to adjust for the straightening/thrusting right arm.
