A portable exercise device for use by a human which includes a helical spring and first and second spaced apart arms adapted for engagement by the human. The arms have proximal and distal portions, the spring biasing the arms toward a first position and permitting them to pivot thereabout to a second position when so urged by the human. The arm proximal portions are joined to the spring so that when the arms are in the first position the proximal portions extend from the spring in the same general direction and are generally parallel to each other and when the arms are in the second position the proximal portions are angled apart from the spring. The exercise device further includes padding mounted on the distal portions for cushioning the human during use of the device. When the device is used as an abduction exercise device, the arm distal portions curve toward each other and each have a generally looped configuration. The arm distal portions can be removed to permit conversion of the device from an abduction exercise device to an adduction exercise device.
A portable exercise device for use by a human through abduction of the upper portions of the legs of the human comprising a spring means, first and second spaced apart arms having proximal portions joined to the spring means and distal portions adapted for engaging the outside of the upper portions of the legs, the spring means biasing the arms toward a first position in which the distal portions are in close proximity to each other, the arms having a length which is sufficient to permit the distal portions to engage the outside of the upper portions of the legs when the arms are in the first position and the upper portions of the legs are in a generally juxtaposed position, the spring means serving as a pivot to permit the arms to move away from each other to a second position when so urged by the human spreading apart the upper portions of the legs, the distal portions being generally curved toward each other with a substantial curvature over a substantial length and serving as means for gripping the outside of the upper portions of the legs so as to retain the device on the legs during use.
A portable exercise device for use by a human through abduction of first and second limbs of the human comprising a spring means, first and second spaced apart arms having proximal portions joined to the spring means and distal portions adapted for engagement by the limbs of the human, the spring means biasing the arms toward a first position in which the distal portions of the arms abut and serving as a pivot to permit the arms to move away from each other to a second position when so urged by the human whereby the abutting of the distal portions of the arms permits a full range of exercise during abduction of the limbs of the human.
A portable exercise device for use by a human comprising a spring means, first and second spaced apart arms having proximal portions joined to the spring means and distal portions adapted for engagement by the human, the spring means biasing the arms toward a first position and permitting them to pivot thereabout to a second position when so urged by the human, and conversion means for altering the configuration of the arms to permit conversion of the device from an abduction exercise device to an adduction exercise device or vice versa.
A portable exercise device for use by a human having first and second limbs comprising first and second arms having proximal and distal extremities, the arms extending in directions so as to cross each other and the distal extremities being formed to be adapted for engagement by the limbs of the human, means interconnecting the proximal extremities and including spring means for yieldably urging the distal extremities in a direction toward each other and permitting yieldable movement of the distal extremities in a direction away from each other under abduction forces exerted by the first and second limbs of the human to provide exercise to the first and second limbs of the human whereby the crossing of the arms hinders deformation of the spring means during use.
