Part 1 of this series introduced the four most common setup and swing faults. It also discussed the importance of having a correct grip and provided a link discussing how to get a proper grip. Part 2 discussed and provided links for posture and alignment.
Part 3 of this series discusses one of the most common swing faults. That is, not staying connected. A connected swing simply means that the hips, torso, shoulders and arms are working in the proper order. See my post on biomechanics for an explanation. Most high handicap golfers get this sequence wrong by letting their arms out pace the rest of their body leading to all kinds of errant shots.
The key to staying connected is to keep the upper left arm close to the chest on the backswing and the downswing, with the right arm reconnecting during the downswing and the follow-through. Here is a link with further explanation and some videos.
Correcting any or all of the setup and swing faults discussed in this series will produce cleaner, crisper shots and contribute to a more consistent and reliable golf swing
