The rotator cuff exercise device includes a ring unit, a mounting board, and a pair of mounting tracks. The rotator cuff exercise device may be adapted to exercise joints and muscles or may prevent the loss of flexibility in an elbow or a shoulder blade. The rotator cuff exercise device may be particularly suited for therapy after an injury involving a rotator cuff. A handle may detachably couple to an individual rotatable ring selected from one or more rotatable rings of the ring unit and may be adapted to be grasped by a hand of the user. The handle may be operable to move the individual rotatable ring in a circular motion. The circular motion of the handle may exercise the joints and muscles of the user.

An exercise device comprises a rigid rod having a first and second ends, a plurality of light sources arranged in a row along at least a portion of an axis extending between the first and second ends of the rigid rod, at least one load sensor for detecting an applied longitudinal force, and a processor coupled to the at least one load sensor and to the plurality of light sources. The processor is configured to execute machine-executable instructions that cause the processor to obtain a signal indicating a magnitude of the applied longitudinal force, and cause a subset of the plurality of light sources to emit light. A ratio of a number of light sources in the subset to a total number of the plurality of light sources represents the magnitude of the applied longitudinal force relative to a reference longitudinal force.

A personal exercise system including an exercise bar having opposing end portions, a grip portion intermediate to the end portions wherein the grip portion is w-shaped, and an elongate resistance band removably secured to at least one of the end portions. Each end portion of the exercise bar includes a loop for accepting a fastener at the end of the elongate resistance band. The loop is operable to pivot about the longitudinal axis of the exercise bar. The system further includes at least one support member each having a groove for receiving an end portion of the exercise bar.

A force measurement mechanism comprises two force input members (105, 106), a pair of cantilever springs (101, 102), and a force measuring means (107). One portion of each cantilever spring is held by a first constraint means (103) and one portion of each cantilever spring is held by a second constraint means (104) with each cantilever spring having an unconstrained length between the first and second constraint means that is free to bend. The constraint means (103, 104) hold the cantilever springs (101, 102) in a parallel and spaced apart arrangement. The force input members (105, 106) are attached via the constraint means so that relative movement of the force input members bends the cantilever springs (101, 02), and the force measuring means (107) is arranged to measure force applied between the force input members.

An exercise apparatus includes a frame and a load mechanism disposed on the frame. The load mechanism has a plurality of selectable weights with each of the selectable weights having an associated indicator device. A press is mechanically coupled to the load mechanism to displace a load based on a selected weight and a sensor is disposed to measure an extent and speed of displacement of the load. A processor is in communication with the sensor, and the processor is configured to determine an indicator signal to send to the indicator device of one of the plurality of selectable weights of the load mechanism based on received performance data, the indicator signal used to indicate which one of the plural of weights to select.
