Play Better Golf with Jack Nicklaus, Jun 8

The more immobile or "frozen" you become at address, the less free and fluid the swing you'll make, and thus the worse the shot you'll usually hit. To stay loose under pressure, be sure to waggle the club at address – to make a few mini-swings of the clubhead away from and back to the ball as you settle into the setup. You'll find there is no better tension-reliever.
