Mike believes many people get too mechanical with their swings because the golf industry fixates on golf positions.
Mike sets up multiple balls in random positions and swings continuously, one after the other hitting each ball. Part of this exercise is to trigger your hand-eye coordination and your athleticism. The key is to get the clubface on the ball.
This exercise is like tennis, where you constantly hit multiple shots in different positions. It is the same as playing baseball and swinging at different pitches.
Continuing this retains your balance and control of the club and puts the clubface on the ball. Your wrist also levers, which creates force.
This drill is fun to do. It takes the mechanics out of the golf swing. Start with a wedge and experiment with different clubs.
Again, this drill gets you back into athleticism and hand-eye coordination rather than positions.
