How to Maintain Width and Stop Your Arms Collapsing in the Backswing
PGA coach SM Golf Coaching explains that maintaining width in the backswing is actually controlled by the trail (right) arm, not the lead arm. By ensuring the right elbow doesn't fold more than 90 degrees and maintaining right-palm pressure on the lead thumb, golfers can prevent arm collapse and improve ball striking consistency.
A perfectly straight lead arm isn't necessary; elite players like Jordan Spieth often have a slight bend.
Width is the distance between your hands and your head at the top of the swing.
The secret to lead arm structure is the trail arm; if the right arm collapses, it pulls the left arm with it.
Limit the trail arm fold to a maximum of 90 degrees to maintain optimal width.
Apply constant pressure with your right palm against your left thumb to help 'push' the club away during the takeaway.
