As the arms swing and the torso rotates, pressure is automatically pulled into the rear hip.

Good golf balance involves the proper channeling of weight flow, and weight is defined in terms of pressure. Think of it this way: Your weight stays the same on earth no matter what configuration your body is in ― standing on one leg, lying down, standing erect, etc.

But the pressure you exert (pounds per square inch) is always changing; it's a dynamic force while weight is static. This is why a 170-pound golfer in spikes doesn't damage the green, but a golfer on a crutch leaves a trail of holes. Pressure is how your weight is concentrated.

At address with the irons, pressure is concentrated approximately 50 percent in the front foot, 50 percent in the back foot, with the toe/heel distribution between the ball of the foot and the heel. At the top of the swing there has been a pressure change (60/40), with concentration on the inner

The arm swing and rotation of the torso put the pressure in the front hip, allowing core rotation. Notice that you can now see the card in this player's back pocket.

edge of the back foot. Front foot concentration is limited to the inner edge around the ball of the foot.

Impact shows a 20/80 distribution with back foot concentration on the inner edge/ball and front foot concentration on the inner edge/ball to heel.

An important role of pressure flow is to allow the body to rotate into the back hip socket on the backswing (coiling) and into the front hip socket during the downswing. If the weight is not flowing into the correct hip socket at the correct time, the swing becomes unbalanced.
