A physiological device and methods for posture correction is described. The device offers a range of active stretching exercise routines to combat poor posture and the development of a protracted shoulder girdle in the user, as well as providing support when worn over the arms. The device comprises two durable loops (1) linked by a central member in a figure-eight fashion, the loops being large enough to fit around the arms and resist slouching in the user. The device includes handles (2) for use in stretching the loops in during the postural correction methods described.
