Clubshaft Control
Purpose:
The golf club should swing with a straight target line. Clubshaft control does not allow the club to swing across the intended target line

Drill:
Use a Cardboard Box

  

Instruction:
Lay down a cardboard box outside the ball pointing in the direction of your target. It helps if the box has some height and length to keep you focused on swinging straight.

Swing the club without hitting the box at any point.

Note:
Please use a cardboard box. This will allow you not to be hurt should you make contact with the box.
