As a PGA coach and inventor Stuart knows ultimate goal to play great golf is to develop effortless speed. Golfers typically force the club through either with an aggressive body (low handicap golfers) or aggressive arms (mid-high handicap golfers) which causes the club head to decelerate and the face to misalign, resulting in compensations. Stuart focuses on 4 key areas of his students swing to develop and gain more speed! Tempo, Rhythm, Transition & Sequencing = Effortless Speed!! In that order! So why the GForce Swing Trainer? You can't force it from the top, this would overload the GForce shaft making it difficult to make contact. For golfers the make and break move is the transition. Look at a professional golfer, they start the downswing from the ground up, the club is the last thing to move so there is very little force applied to the handle of the club in transition preventing the shaft from overloading. For amateur golfers it is the opposite, they start from the top down applying all their force to the handle in transition overloading the shaft so the sequencing is out from the off!! You will never play good consistent golf this way.The key is to focus on keeping the GForce shaft rigid throughout the swing. It is a good idea to video yourself using the swing trainers for the first time so you can see the shaft flex and see how you develop over time to achieve a more rigid look in the shaft when you swing. It is very clear to see professional golfers swing without effort like a finely tuned athlete performing their task, running, gymnastics etc, because they sequence the movement and repeat it over and over again to make it permanent so they perform without any thought. Use it at home for swing training and hit balls on the practice range, combining the two together will give you the best golf swing workout on the planet... Instantly feel when your swing is out of sync through the feedback from the shaft and the flight of the ball. Good luck ;-)
