backswing question

[Humble_Guru]

Hello everybody, this is my first post here.

At the top of my swing my back seems like its got a big hollow in it but looking at pro's their backs look so straight from the hip to the shoulders at the top of the backswing.

Whats the difference between me and them?

Keeping in your spine angle and learning to turn your tummy in a level fashion is the difference.

Try putting your butt against a chair or wall, your rear end should be in contact all the way until you come out on the finish.

Remember level turn not tilt...and move the weight pressure into your RS...

Sounds like your TAILBONE has moved TOWARD the target on backswing.

It should stay in the same place.
