One of the poses I love to work, and especially with glamour, is a pose on the ground. Choose a longer lens and a wider aperture and "pinpoint" light, for example a beauty dish with grid from pretty close by, some reflective or other nice material and everything is set for some interesting poses on the ground. Depending on the body of the model the poses will have to be changed, personally I love to see more rounded lines, with the more plus sized models you can use oversized mens shirts to cover up the areas that the model wants and "shape" her body that way. Overall I always find these poses to be very pleasing and also work great with starting models. Change your own position and move around your model to maximize the results.
