I found if you think of the horses legs being your legs helps, as trot is a two time diagonal gait and if you can imagine trotting you self it helps. Relax yes but make sure you keep you upper body posture correct at the same time. Don't slump.
I love sitting trot (I am lazy and rising trot uses up more of my energy.)
