Keep your tilt to the ball to strike it first
To hit crispy, clean contact, keep your body's relationship (tilt) to the ball throughout the entire golf swing so you strike the ball first and take a nice divot in front of it. The speaker says all professional golfers keep this tilt to the ball and that is why they hit it so solid, while most amateur golfers lose their tilt to the ball, causing inconsistent contact.
