Your lateral body shape is your body in profile or the side view.
Round Lateral Body Shape
The round lateral body shape is more common on the O shape, X shape, 8 Shape and A Shape horizontal body shapes. Of course I have seen the H shape and V shape as rounded lateral body shapes as well!
Elliptical Lateral Body Shape
The H shape, V shape and I shape are most commonly elliptical, though I do know of A shapes and X shapes who are elliptical.
