A punching bag with multiple strike targets features a punching bag body, a plurality of cutouts, and a plurality of strike targets, the punching bag body extending between an upper end and a lower end. The plurality of cutouts traverse into the punching bag body and provide spaces within which the plurality of strike targets are connected. An upper strike target is positioned within an upper cutout, representing an opponent's head, and a lower strike target is positioned within a lower cutout, representing an opponent's midsection. The punching bag body may be hung from an elevated mounting point by a plurality of straps connected to the upper end of the punching bag body, or the punching bag body may be supported above a floor or other surface by a base connected to the lower end of the punching bag body.

FIG. 7 shows an air cannon system loaded with a launch canister containing a prop-fouler. A pressure vessel (28) contains an inlet including a poppet valve (100) that, upon command, can be selectively placed in either a one-way flow position to permit charging of the pressure vessel or otherwise opened to trigger rapid discharge through pressure equalization with the ambient environment. The air cannon may include multiple splayed barrels or a single barrel (158). A launch canister (202), realized in the form of a tube, has a driving plate (350) that closes an end of the launch tube. The driving plate is the first point loaded into the barrel. Within the launch canister (202) a first portion of a floating prop-fouling line is stored. The prop-fouling line, such as made from Dyneema, has at its ends two drogues that, upon entry into the water, fill with water to produce drag resistance to movement of the prop-fouling line. To avoid undue stress on canopy panels of each drogue and to avoid twisting of shroud lines (312) to the canopy, a rotating shackle (310a, 310b) acts as a coupling point between the shroud lines (312) and the prop-fouling line. Only one drogue (306), its associated coupling and a selected length prop-fouling line are loaded into the launch canister, with the other drogue and its rotating shackle (310b) loaded into a cradle (166). Upon firing, gas expansion causes the rapid acceleration and ejection of the launch tube (202) and generally straight line deployment of the prop-fouling line (302).

A portable shield made for individuals who practice boxing, martial arts, or any combat sport. The portable shield comprises a central striking area, a resilient neck-like striking area, a head-like striking area that are suitable for kicking and/or punching. The portable shield also comprises holding arms for steering the shield and a spring within the resilient neck-like striking area for allowing movement of the head-like striking area when it is stricken by a user/athlete. The head-like striking area, the resilient neck-like striking area and the central striking area are covered with padding material to prevent injuring the user/athlete when kicking and/or punching.

An exercise bench for use by a person on a support surface includes a base member having a distal end, a proximal end, a top surface, and a bottom surface. A pair of opposing foot restraints is fixed with, and disposed above and laterally away from, the base member. A riser projects upwardly from the proximal end of the base member and includes a calf restrain trolley slidably mounted thereon. A base plate can be fixed with the bottom surface of the base member, and a U-shaped base extension having two legs extending away from the proximal end of the base member can be attached to the proximal end of the base member. A plurality of attachments may be coupled to the bench to provide different exercises.

A tension adjustment structure of a boxing training device contains: a base, at least one control module for controlling a tension of a spring, and an impact module. The base includes a first fitting tube and a first screwing element. The impact module includes a coupling stem. The at least one control module includes a first support post, the spring, a second support post, a second fitting tube, and a second screwing element. The coupling stem is inserted through the first support post and the second fitting tube, and the second screwing element is screwed into a locking orifice of the first support post to fix the coupling stem in the first support post and the second fitting tube. The spring is partially fitted on the first and second support posts, and a height of each of the first support post and the second support post is adjustable.

A semi-submersed floating striking exercise device with a striking portion to be filled with water, a floatation portion at least partially above the striking portion, the floatation portion to be filled with air and an above-the-water portion to be filled with air, the above-the-water portion positioned above the floatation portion. The striking exercise device also includes at least one of a handle and/or an attachment device, at least one air inlet for inflating the floatation portion and the above-the-water portion, and a water inlet for filling the striking portion with water. The striking exercise device optionally includes a tether with a first end and a second end, and a tether harness to be worn on a user, wherein the first end of the tether is attachable to the semi-submersed floating striking exercise device and the second end of the tether is attachable to the tether harness.

A portable shield made for individuals who practice boxing, martial arts, or any combat sport. The portable shield comprises a central striking area, a resilient neck-like striking area, a head-like striking area that are suitable for kicking and/or punching. The portable shield also comprises holding arms for steering the shield and a spring within the resilient neck-like striking area for allowing movement of the head-like striking area when it is stricken by a user/athlete. The head-like striking area, the resilient neck-like striking area and the central striking area are covered with padding material to prevent injuring the user/athlete when kicking and/or punching.

A striking practice device includes a striking body, a cover, a connecting rod and an outer fixing plate. The striking body includes a hollow portion inside, an assembly hole formed along a direction of the striking body and a cover bole formed along another direction of the striking body. The assembly hole has an inner junction at the hollow portion of the striking body and an outer junction outside the striking body; the cover has a shape corresponding to the cover hole for sealing the cover hole; the connecting rod is installed to the assembly hole and has an inner fixing plate at an end; the inner fixing plate is greater than the assembly hole and disposed at the inner junction; and the outer fixing plate is fixed to the connecting rod and the outer junction of the striking body.

A supporting device for a punching bag includes a hollow tubular pillar; a connector; a flange body; a rubber shock absorber; and a support tray. The connector includes a first end and a second end; the second end is bigger than the first end in diameter; the first end is disposed into the hollow tubular pillar. The connector includes a first connection hole, and the hollow tubular pillar includes a second connection hole. The connector and the hollow tubular pillar are fixed by a locking screw through the first connection hole and the second connection hole. The flange body includes a central blind hole, and the second end of the connector is disposed into the central blind hole. The flange body further includes a radial base. The circumference of the radial base includes a plurality of mounting holes configured to receive a counterweight unit to stabilize the supporting device.

A training device has a joint function suitable for training various complex motions for various body parts such as an arm, a leg, a head, and a trunk for training martial arts. The training device includes: a shaft; a joint having a diameter larger than that of the shaft and disposed at one end portion of the shaft; a joint support contacting the joint and elastically supporting the joint; and a shaft support elastically supporting an outer side of the shaft at the one end portion of the shaft.
