The proximal end of the handle is rotatably connected to the first end of the swing arm, allowing the swing arm to rotate around the proximal end of the handle in a “clock-hand” fashion. A connecting shaft and swing arm stopper prevent the swing arm and handle from becoming separated during use. The exercising device may further have a weight member positioned in a weight member recess located close to the second end of the swing arm. The weight member increases the difficulty of using the exercise device and is removably attached to the swing arm. A safety sleeve can fit over the weight member recess to prevent the weight member from dislodging during use. ## Claims ### Claim 1 An exercising device, comprising: a handle having a proximal end and a distal end; a swing arm having a first end and a second end, wherein the proximal end of the handle is rotatably coupled to the first end of the swing arm thereby allowing the swing arm to rotate around the proximal end of the handle; a connecting shaft disposed on the proximal end of the handle, wherein there is a shaft hole located near the first end of the swing arm, and wherein the connecting shaft is inserted into the shaft hole; a swing arm locator removably coupled to the connecting shaft thereby preventing the connecting shaft from disengaging from the shaft hole, wherein the connecting shaft has a shaft diameter larger than a diameter of the handle. ### Claim 2 (depends on 1) The exercising device of claim 1, wherein holding the handle and wielding the exercising device drives the swing arm to rotate around the proximal end of the handle. ### Claim 3 (depends on 2) The exercising device of claim 2, further comprising: at least one weight member, wherein the at least one weight member is capable of being removably coupled to a weight member recess located in the swing arm. ### Claim 4 (depends on 3) The exercising device of claim 3, further comprising: a safety sleeve capable of being removably coupled to the swing arm and partially or wholly covering the at least one weight member recess thereby preventing the at least one weight member from becoming disengaged from the weight member recess. ### Claim 5 (depends on 1) The exercising device of claim 1, further comprising: a grip cover covering the handle. ### Claim 6 (depends on 1) The exercising device of claim 1, further comprising: a handle strap having an anchoring end and an adjustable end, wherein the anchoring end is coupled to a connecting shaft and the adjustable end removably couples to the distal end of the handle. ### Claim 7 (depends on 6) The exercising device of claim 6, wherein there are a plurality of adjustment holes disposed on the handle strap and wherein there is a protruding member on the distal end of the handle, wherein the protruding member is capable of being removably inserted into each of the plurality of adjustment holes. ### Claim 8 (depends on 7) The exercising device of claim 7, further comprising: a handle cap capable of coupling to the distal end of the handle thereby preventing the adjustment end of the handle strap from being detached from the distal end of the handle. ### Claim 9 (depends on 1) The exercising device of claim 1, wherein the swing arm has a first section in proximity to the first end and a second section in proximity to the second end. ### Claim 10 (depends on 9) The exercising device of claim 9, wherein the first section is perpendicular to the handle, and the second section and the handle form an obtuse angle. ### Claim 11 An exercising device, comprising: a handle having a proximal end and a distal end; a swing arm having a first end, a second end, a shaft hole proximally located to the first end, and a weight member recess proximally located to the second end, wherein the swing arm has a first section located proximally to the first end, and a second section located proximally to the second end, and wherein the first section is perpendicular to the handle, and the second section and the handle form an obtuse angle; a connecting shaft coupled to the proximal end of the handle, wherein a front end of the connecting shaft is inserted into the shaft hole thereby allowing the first end of the swing arm to be rotatably connected to the proximal end of the handle, and wherein holding the handle and wielding the exercising device causes the swing arm to rotate around the proximal end of the handle, and wherein the connecting shaft has a shaft diameter larger than a diameter of the handle; a swing arm locator removably coupled to the connecting shaft thereby preventing the connecting shaft from dislodging from the shaft hole; a weight member, wherein the weight member is positioned in the weight member recess and removably coupled to the swing arm; a safety sleeve removably coupled to the swing arm and partially or wholly covering the weight member recess thereby preventing the weight member from disengaging from the weight member recess; a grip cover covering the handle; a handle strap having an anchoring end and an adjustable end, wherein the anchoring end couples to the connecting shaft, and wherein the adjustable end is removably coupled to the distal end of the handle; and a handle cap capable of covering the distal end of the handle thereby preventing the adjustment end of the handle strap from becoming detached from the distal end of the handle; wherein the handle has a length of about 12 cm to about 18 cm, the first section of the swing arm has a length of about 6 cm to about 9 cm, the second section of the swing arm has a length of about 20 cm to about 30 cm, the handle has a diameter of about 2 cm to about 4 cm, and the connecting shaft has a diameter of about 4 cm to about 8 cm. ### Claim 12 (depends on 11) The exercising device of claim 11, wherein the swing arm and the handle are made from plastic, the weight member is made from metal, the safety sleeve and the handle strap are made from rubber, and the grip cover is made from foam. ### Claim 13 (depends on 11) The exercising device of claim 11, wherein there are a plurality of adjustment holes on the adjustable end of the handle strap and wherein there is a protruding member on the distal end of the handle, wherein the protruding member is capable of being inserted into each of the plurality of adjustment holes. ### Claim 14 (depends on 12) The exercising device of claim 12, wherein the connecting shaft has a swing arm stopper, the swing arm being blocked by the swing arm stopper thereby preventing the front end of the connecting shaft from disengaging from the shaft hole.
