TWO VARIABLES for Solid Contact -
Top players have learnt to reduce the swing to three component parts, movement from the centre, the strike and pacifying the arms.

To hit the ball out of the sweet spot there are two variables:
1. Maintain spine angle and
2. Undisturbed triangle.

It really is simple geometry, we must not force the movement and it all goes back to the core training of the body. Body turn, hand action and turn back and through.
