The swing is an arc from an above and inside the ball view. The clubhead should travel along the target line for a few feet before it starts arcing back to the inside. Here is a drill to help achieve that.
Many people talk about Mac Ogrady in awe with regards to his swing and teaching philosophy. It is really no different to what I teach. This video shows him talking about what equates to drill 1- 2 and 3.
Proper balance and proper ground forces does not ask for the left foot to jump upwards or backwards. This is a sign of a stalling body and is an attempt to try keep the body moving. There is a better way.
Getting the shoulders to turn correctly pays huge dividends for the direction the arms and club move and how the body works. Proper sequence is everything. Watch to learn the desired shoulder movement.
Most golfers are under the wrong impression as to when and where speed of the clubhead comes from. It's why mastering the 430 release is not only a key to straighter shots but also longer shots too.
A question I often get asked- Is why the forearms? This video will clear up why that is the focal point of the release rather than the hands themselves.
