The present invention is directed toward an exercise machine and climbing simulator that enables its users to initiate the climbing or crawling motion whilst being rotated at different angles. This invention includes a rotatable framework and a plurality of foot spines and arm spines that are configured to support the feet and arms of a user. As the framework rotates, the user incurs exercise in maintaining contact with the plurality of foot and hand spines. Each of the foot and hand spines is decoupled from each other, that is, each of the foot and hand spines is configured with independent rotational and lateral movement. By changing the angles of rotation and the positions of the foot and hand spines, gravity is applied in different ways and therefore different muscle groups are targeted. Thus, this invention assists users in acquiring varying degrees of physical fitness and mountain climbing preparation.

[Problem] During a lowering exercise according to the prior art, changes in upper-limb (forearm, elbow joint, and shoulder joint) movement are such that, since the rotation axis of a grip part is fixed in the vertical direction, the hand rotates around the vertical axis together with the grip part as the lowering exercise is executed, and the shoulder joint continues to internally rotate. As a result, the forearm keeps inclining forward, thereby restricting subsequent extension acceleration slightly rearward of the body. [Solution] Provided is a training machine with which training is performed by moving an arm unit against the weight of a back weight, the arm unit being connected to at least one back weight via a cable and vertically movable along a guide column. A grip part of the arm unit is configured to rotate around an axis substantially orthogonal to the guide column axis. A training machine can thus be provided which can accommodate changes in the inclination angle of the hand and does not restrict extension movement when the upper limb is extended while being lowered.

A device for relieving the right shoulder muscles of a right-handed player when playing a stringed instrument, while simultaneously utilizing the resulting free fall force of the right arm to stabilize the instrument. The device consists of a body support that connects the upper bout of the instrument to the player's torso and an armrest that attaches to the rib of the upward-facing lower bout of the instrument, allowing the right upper arm to rest comfortably. When playing a stringed instrument, the right arm must be constantly held in a forward-raised and laterally abducted position due to the instrument's size, using muscle strength to prevent its weight from altering the instrument's playing position. The armrest allows the upper arm to rest comfortably, thus completely relieving the right shoulder muscles. The body support prevents the upper bow of the instrument from being levered forward and upward when the right arm, with its falling force, acts backward and downward on the lower bow. The device causes the force of fall released by the relaxation of the right shoulder muscles to clamp and fix the instrument between the arm, the leg on which it stands, the body support and the contact point between the base of the instrument and the upper body of the player.
