With the Symple Swing, a dominant bottom hand could accidentally close the clubface at impact.
We use the “squeeze test” to make sure that any tension in the grip will not close the clubface
during a full power swing.
1. To check your grip, first take your grip normally on the club.
2. Then stretch the club out in front of you near horizontal. Without tension in your hands and
arms the clubface should be square (vertical).
3. Then tense your arms, your forearms and your hands. Squeeze the club very tightly. If the
clubface closes during this drill, it is also likely to close during a full swing, especially a swing at
maximum power. If this happens, be certain that both your thumb and index finger are “pinched”
to each other and completely off the grip of the club.
The purpose of this test is to see if your grip will keep the clubface square at impact. It does this
by simulating the flexing (tension) of the muscles during a full power swing.
