A connected rotational takeaway will always work inside. If it is a PW the wirsts will hinge early, if a driver they will hinge later due to wider arc.

Try and feel one of the following and see which works best for you

1. Push the club back with the heel of left hand at a 45 degree angle

2. Push the triangle back with your left shoulder at a 45 degree angle

3. Turn the chest (and triangle) so that your back faces the target

In all of these you should be turning and not swaying right and the hands/wristrs should be really soft and not controlling the swing path

Personally I swallowed the low and slow advice when I started and I didnt understand what it meant. I therefore tried to use my hands to take the club straight back along the target line for as far as I could go. Very steep, disconnected and usually a sway to the right or reverse pivot. Once I learned low and slow meant along an inside circular path (i.e. an imaginary 45 degree line) then it all clicked !
