Address: A proper address aligns your entire body in the optimum, well-balanced position necessary for a powerful swing. Without correct positioning, your swing is doomed from the start. A golf teaching aid for the address phase of your swing needs to guide and monitor the positioning of your feet, body and the ball. For example, The Power Stance guides your feet into the proper position during the address portion of the swing, improving your balance, weight transfer, swing tempo, flexibility, ball position and alignment (apvgolf.com). Another type of golf teaching aid designed to help your address is a visual alignment tool. One such tool is the EyeLine Practice T & Mirror, which allows you to check your ball positioning and alignment of your head and shoulders (eyelinegolf.com).
Backswing: During the backswing, you load up the energy that will be used to power your downswing. In order to generate the most energy, your body and club must keep the correct alignment, with your swing passing along the correct plane. A good swing on the correct plane is when you have an outside takeaway, which is when you swing the club far away from your leg. A golf teaching aid for your backswing must prevent an inside takeaway, which is when you bring the club too close to your body. Devices that define the proper swing plane are good teaching aids for your backswing. The Plane Stick, for example, prevents an inside takeaway by forcing you to swing around its guide arm. If your backswing is incorrect, you will hit the guide, giving you instant feedback (intheholegolf.com). The Takeaway Trainer, on the other hand, attaches to your back thigh and has a pad that sticks out perpendicularly from the front of your leg. It also forces you to have an outside takeaway (takeawaytrainer.com).
Transition: The transition phase of your swing converts the energy produced during your backswing into the driving power of your downswing. A golf teaching aid for your transition should help you align your arms in such a way that your club can follow the path of least resistance, maximizing the returns from your stored force. One type of device that can teach you correct arm alignment is a brace. Braces for elbows and wrists are commonly used to teach a good transition. The Swing Extender, for example, attaches to your right bicep -- for right-handed golfers --, preventing your back arm from over-collapsing (swingextender.com). Anther bracing device is the Right Angle 2, which fits around your back forearm and upper arm. It prevents your arm from folding more than 90 degrees, correctly positioning it for a powerful downswing (intheholegolf.com).
Downswing: During the downswing, you utilize all your body's stored energy to create maximum, controlled force at impact with the ball. Correct club path and tempo are essential for distance and accuracy. A golf teaching aid for your downswing should work on swing path, swing plane and tempo. Modified clubs -- both hinged and flexible -- and swing path guides can be useful. For example, Whippy TempoMaster Clubs have flexible shafts that allow you to feel what you are doing wrong in your swing and eliminate an over the top swing (tempomaster.com). A swing path guide, such as the Inside Approach, can help you develop the proper swing path through the impact zone, which enables you to hit powerful, accurate shots (info.insideapproach.com).
Follow-through: Although the follow-through doesn't affect the flight of your ball, it is useful in recognizing flaws in your swing. A proper follow-through travels along the same path as your downswing. Any deviation from that plane, wobble in your balance or breaking of the arms and wrists is a sign that something in your swing is off. A golf teaching aid for your follow-through should help you recognize signs of a swing error. Laser guides are useful in monitoring the plane of your follow-through. For example, Plane Sight is a laser light that attaches to the butt of your club. By monitoring the image projected on the ground during your follow-through, you can tell if your swing is vertical, flat or on plane (planesight.com). Full circle swing trainers -- circular frames that define you swing plane -- can also aid your follow-though. The Super Swing Trainer, for example, is an adjustable PVC frame that guides your swing and follow-through along the optimal plane. If your follow-through is off, you will hit the frame, alerting you to the error (superswingtrainer.com).
Each phase of your golf swing must be done correctly to hit the ball well. If you need help in a particular area, there is a golf teaching aid available that can help fix your swing. Your job will be to determine which area needs the most help.
