“Cupped” is usually used to describe a poor position of the hands at the top of the backswing – it would be with your left wrist bent back toward your forearm. It could also be a position at impact when you have released the hands way too early. In either case it is not something you want.

It depends on the context of “cupped”. But generally this is referring to a bowed wrist at impact or at the top of the backswing. Bowed meaning, at impact, the wrist would pointed at an extreme angle towards the target almost pointing towards the ground. In the backswing a cupped wrist would be pointing toward the sky.

You want to have a slightly bowed wrist at impact, i wouldnt suggest it at the top of the backswing. However, David Duval was very succesful with a bowed wrist at the top of his swing….then he fell off the map.
