Golfers who are on the back nine of their lives, or in other words getting old and crumpled, can still enjoy a round of golf if they stop reminiscing of earlier days of smacking the ball way down the middle, with seamlessly no effort at all.
A common concern among old, long-winded golfers is how to regain the distance they once had in their youth, without increased risk of injury. Unfortunately for older golfers, most modern-day golf instruction available includes intensive swing speed training that just isn't a suitable approach. To gain more distance or to keep the yardage that you have -- focus on staying healthy and concentrate on a more straightforward approach that focuses on the setup rather than raw power in the golf swing.
Look carefully at your setup as setup adjustments, whilst recognising the limitations that come with age, particularly the inevitable reduced flexibility of old bones and tendons. Whether we like it or not, getting old will restrict our rotational/turning capacity. One way of optimising this setup is pulling the right foot back slightly. By doing so you'll have a slightly closed stance, and in turn, a longer backswing. The backswing's length is directly proportional to the distance achieved -- a longer backswing translates to more power.
Out of Bounds: Practice keeping a wider stance, pull your right foot back, and concentrate on the right hip and shoulder moving up and back during the backswing. This creates a more extended backswing and, consequently, a more powerful strike.
