It is important to start any exercise in a position that is tension-free. If there is already tension before starting, too much stress will be created once movement begins.
This doesn't mean complete relaxation, though. For example, when lying on your back with pelvis and spine neutral, a slight activation of the muscles will be necessary to maintain pelvic, rib cage and spinal placement.
