An exercise device is provided that comprises a support arm having an upper support arm member defining an upper support arm axis and a lower support arm member defining a lower support arm axis. The exercise device further comprises a support structure to which the support arm is pivotably attached by a longitudinal pivot mechanism and a lateral pivot mechanism. The longitudinal pivot mechanism is adapted so that the support arm may be selectively rotated about a longitudinal pivot in a pitch plane that includes the upper support arm axis. The longitudinal pivot mechanism is also adapted so that the support arm may be selectively locked at a selected pitch rotational position. The lateral pivot mechanism is adapted so that the support arm may be selectively rotated about a lateral pivot point in a vertical plane that is orthogonal to the pitch plane. The lateral pivot mechanism is also adapted so that the support arm may be selectively locked at a selected lateral rotational position. The exercise device also comprises a yoke pivotably attached to the upper support arm at a yoke attachment point so that the yoke may be rotated about the upper support arm axis. The yoke is adapted for being grasped by a user for rotating the yoke about the upper support arm axis.
