During down time its so easy to lose your “feel” of your swing. Doing just 15 minutes a day of the drills that keep you “in touch” with your swing can keep you sharp when you get back on the course. If you don’t have some drills in mind I suggest the following (1) Feet together, ball on a tee using a 7 or 8 iron with the idea being to make roughly half distance shots with a slight draw. The half swings should stop where the lead arm ( left arm for a right hander) is parallel to the ground in the backswing, then the arms drop and rotate to the target side with the trail arm parallel ( right arm for a right hander) in the through swing.
This a great drill for players of all ability levels….you may be surprised at how solid and far the ball goes!
