The middle section interconnects the thumb section with the grip section. The middle section biases the thumb section away from the grip section. Wherein, when the grip section is held in the user's fingers similar to a grip of the firearm, the thumb section is oriented approximate a user's extended thumb similar to the hammer of the firearm. Wherein, the user may grip the grip section with their fingers and depress the thumb section with their thumb. Whereby, the thumb exercise device simulates the feel and action of backing the hammer of the firearm. ## Claims ### Claim 1 A thumb exercise device for simulating the feel and action of backing a hammer of a firearm comprising: a thumb section; a grip section; and a middle section that interconnects said thumb section with said grip section; said middle section biases said thumb section away from said grip section. ### Claim 2 (depends on 1) The thumb exercise device of claim 1, wherein, when said grip section is held in a user's fingers similar to a grip of the firearm, said thumb section is oriented approximate a user's extended thumb similar to the hammer of the firearm; wherein, the user may grip the grip section with their fingers and depress the thumb section with their thumb; whereby, the thumb exercise device simulates the feel and action of backing the hammer of the firearm. ### Claim 3 (depends on 2) The thumb exercise device of claim 2, whereby, the thumb exercise device simulates the feel and action of backing the hammer of the firearm with slightly greater resistance. ### Claim 4 (depends on 1) The thumb exercise device of claim 1, wherein said thumb section includes a surface sized to receive the user's thumb. ### Claim 5 (depends on 4) The thumb exercise device of claim 4, wherein the surface is substantially flat and oriented approximately horizontal when the grip section is held in the user's fingers similar to the grip of the firearm. ### Claim 6 (depends on 4) The thumb exercise device of claim 4, wherein the surface has a rounded distal end for contact with the user's thumb. ### Claim 7 (depends on 4) The thumb exercise device of claim 4, wherein said thumb section includes a thumb pad on said surface. ### Claim 8 (depends on 7) The thumb exercise device of claim 7, wherein said thumb pad is plastic or urethane. ### Claim 9 (depends on 1) The thumb exercise device of claim 1, wherein said grip section includes a cover with a shape similar to the grip of the firearm. ### Claim 10 (depends on 9) The thumb exercise device of claim 9, wherein the cover is urethane or rubber. ### Claim 11 (depends on 1) The thumb exercise device of claim 1, wherein the middle section includes a trigger finger hole sized like a trigger hole of the firearm configured to receive a trigger finger of the user. ### Claim 12 (depends on 11) The thumb exercise device of claim 11, wherein the trigger finger hole includes a trigger surface positioned like a trigger of the firearm inside the trigger finger hole. ### Claim 13 (depends on 12) The thumb exercise device of claim 12, wherein the trigger surface is integral with a cover of the grip section. ### Claim 14 (depends on 1) The thumb exercise device of claim 1, wherein the middle section including a spring coil terminating at one end with the thumb section and at the other end with the grip section. ### Claim 15 (depends on 14) The thumb exercise device of claim 14, wherein the spring coil including one coil in the middle section for biasing the thumb section from the grip section. ### Claim 16 (depends on 14) The thumb exercise device of claim 14, wherein the thumb section end of the spring coil including: a thumb angle from the spring coil configured to orient a surface of the thumb section approximately horizontal when the grip section is held in the user's fingers similar to the grip of the firearm; and a thumb loop after the thumb angle configured for making the surface of the thumb section. ### Claim 17 (depends on 14) The thumb exercise device of claim 14, wherein the grip section end of the spring coil including: a first grip angle and a second grip angle from the spring coil configured to orient the grip section; and a grip loop after the first grip angle and second grip angle configured to support the grip section. ### Claim 18 (depends on 14) The thumb exercise device of claim 14 wherein the spring coil is a steel spring coil. ### Claim 19 (depends on 1) The thumb exercise device of claim 1, wherein the firearm is a single action revolver. ### Claim 20 A method of exercising the thumb comprising: providing a thumb exercise device comprising: a thumb section; a grip section; and a middle section that interconnects said thumb section with said grip section; said middle section biases said thumb section away from said grip section; gripping the grip section with a user's fingers similar to a grip of a firearm; and depressing the thumb section with the user's thumb.
