Abstract: An air resistance device to be held in the hand of user while undertaking exercise, this device having a grasping portion and a frame portion. The grasping portion comprises a relatively straight member upon one end of which an arm clamping member is disposed, and adjacent the other end of which a handle to be grasped by the hand of the user is disposed. The frame portion is attached adjacent the handle and is of elongate rectangular configuration, with its length exceeding its width. The length of the frame portion extends generally in the same direction as the relatively straight member. The frame portion is relatively rigid and configured to receive a membrane thereon through which air cannot easily pass. Therefore, upon a membrane being attached to the frame portion, a user can derive exercise by attempting to move the device rapidly against the resistance of the ambient air. Different versions of a foldable handle arrangement are taught, and the membrane may be integral with the frame portion.

Abstract: The present invention is an exerciser for a user. It has a main body that includes a main frame, a top portion, a bottom portion, and an intermediate portion. The bottom portion contains only one single lower belt rung and only one second lock pin. The single lower belt rung is steel. Belt rungs attach the main body to the user so that the user can exercise inconspicuously. The top portion contains a pair of upper belt rungs and a first lock pin. Additionally, included is an "S"-shaped bar having a free end at which said "S"-shaped bar is pivotally connected to a crank handle which is gripped by the user.
