I stumbled upon these old videos on YouTube by Michael McTeigue and they are probably the best step-by-step guide to fixing or building a golf swing. The Videos are ancient but these golf video tutorials all totally still stand up. I believe they are from an old VHS golf instructional offering and converted to digital for YouTube.
I will attach the videos below but I should also note that after seeing these videos I also bought Michael McTeigue's book, "The Keys to the Effortless Golf Swing: Curing Your Hit Impulse in Seven Simple Lessons," which offers a concise roadmap to elevate your swing to new heights. Here is the book link on Amazon.
Here is a basic rundown of the book and videos. Really I find the most valuable part the teaching of the basic body turn or body coil and his explanation of how you should shift your weight in the golf swing. Helped me a ton.
Shift Your Mindset: McTeigue emphasizes transitioning from a "hit" mentality to a rhythmic, flowing motion, setting the foundation for an effortless swing.
Embrace Balance: Achieve consistency and power by perfecting your setup and posture, leveraging your body's natural mechanics.
Build the Coil: Create torque and potential energy by mastering the art of coiling during the backswing.
Smooth Transitions: Seamlessly move from backswing to downswing, eliminating abrupt shifts that lead to mishits.
Unleash the Release: Timing and sequencing are keys to releasing stored energy effectively, maximizing the clubhead's impact.
Connect Your Movements: Foster coordination between hands, arms, and body, ensuring a fluid, synchronized swing.
Harmonize with Rhythm: Master rhythmic motion by integrating all elements, culminating in a cohesive, effortless golf swing.
McTeigue's step-by-step approach really demystifies the swing. It will help you tweak your golf swing as it did me or offer new beginner golfers a simple and clear path to golf swing. Whether you're a novice or a seasoned player, "The Keys to the Effortless Golf Swing" provides invaluable insights, transforming your swing into a powerful, fluid, and effortless motion on the golf course. Enjoy!
