BUILDING A STABLE BASE
THE DRIVER & WOODS FROM THE FAIRWAY . . .
My feet are spread wide to accomodate my big shoulder turn and faster upper-body movement during the swing. A narrower stance would encourage a sway; a wider stance would limit my weight shift.
ON EVERY SHOT: You need a combination of balance, stability and ease of movement. Those factors are largely determined by stance width - how far apart you position your feet at address. Stance width is especially important with your irons, as they are precision clubs that demand a rock-solid base with your lower body.
SHORT SHOTS: My swing with the short irons isn't super long, and I rarely swing with all my effort; therefore, I don't need a wide base. When I'm pitching or chipping, my stance is narrower still.
THE (5) IRON: As the club becomes shorter, my stance width becomes narrower. My stance is wide enough to allow me to keep my balance, but not so far apart that it restricts motion in my upper body. With each club, it is important to be consistent with my stance width on every shot. That is the only way to produce consistent results.
THREE (3) THINGS HAPPEN WHEN I CHOKE DOWN ON MY IRONS:
1. I hit the ball a bit straighter
2. I get a lower ball flight
3. The ball doesn't check up as quickly when it hits the green.
