WeldConstraints don't work properly when used on a player?

So, basically I am assuming many of you have seen what welding objects to a player can do, Here is an example of it.

It is almost as if I am rotating around it when I turn instead of it going around me, this also speeds the character up slightly when turning.

Does anybody know a way around this without changing it to BodyPosition, etc?
