A quick folding agility ladder and methods of folding and opening the agility ladder are disclosed. In one embodiment, the quick folding agility ladder can comprise a plurality of rectangular ladder frames and a plurality of ladder rung sleeves connecting the rectangular ladder frames. The plurality of ladder rung sleeves can comprise a first rung sleeve and a second rung sleeve. The agility ladder can be folded into a quadrifolium configuration comprising four petal-shaped portions including a first petal-shaped portion, a second petal-shaped portion, a third petal-shaped portion, and a fourth petal-shaped portion. The first rung sleeve can form at least part of the first petal-shaped portion and the fourth petal-shaped portion and the second rung sleeve can form at least part of the second petal-shaped portion and the third petal-shaped portion.

The present invention provides a game racquet including an integrated circuit capable of supporting a low-voltage energy current. An embodiment of the invention provides a game racquet including one or more enhancements attached or integrated on the racquet frame. These enhancements may include but are not limited to: one or more LEDs, a sound amplification device, and an electromagnetic vibration emitter. In a further embodiment, the game racquet responds electronically to ball impact on at least one of the strings, and subsequently performs and action or actions including but not limited to making a sound or sounds, triggering lights, triggering LEDs, triggering another type of automation on the racquet such as a vibration emitter within the handle. The game racquet frame comprising at least one string channel in the frame head, bridge, or other area, which houses an actuator responds mechanically to a string movement triggering electronic connection.

A punching bag and suspension system is a boxing training device that is orientated horizontally, which permits the punching bag to move vertically, horizontally, diagonally, as well as a 360 degree range of motion. The punching bag has a plastic or metal cylindrical tube running through its core. The tube contains an opening on both sides extending to an outer circumference of the punching bag. These openings allow the tube, and therefore the punching bag, to slide along suspension member.

A sports training safety system and method of operation thereof includes: a training dummy; a magnetic release attached to the training dummy; a delivery carriage mounted to the magnetic release; a delivery rail for supporting the delivery carriage; and a transport system, attached to the delivery rail, for moving the delivery carriage and the training dummy along the delivery rail.

In one implementation, a game apparatus includes a base with a playing surface that has (i) a first end with a first designated area for cups and (ii) a second end; a game piece; a tether that attaches the game piece to the base so as to permit the game piece to move freely within the tether's range; and a first launcher that includes a mechanism to launch the game piece as a projectile, the first launcher being positioned at or around the second end to launch the game piece toward the first designated area for cups, wherein the first designated area for cups and at least a portion of the first launcher are within the tether's range.

An exercise apparatus or machine according to the present disclosure is adapted to support a user above a floor while the user performs hip thrust or other exercises. The exercise machine includes a head support and a foot support for supporting the torso and feet of a user so that the hips of the user are suspended in an exercise area between the head support and foot support.

A combined golf club cover and stand comprises a substantially rigid base and a cover portion configured to securely hold a head of a golf club against the substantially rigid base. The substantially rigid base includes a bottom platform, a first side wall, and an opposing second side wall with a bottom ledge that extends toward the first side wall, such that when the head of the golf club is held against the substantially rigid base, a toe end of the head is in contact with an interior surface of the first side wall, and a heel end of the head sits on the bottom ledge of the second side wall. The assembled golf club and combined golf club cover and stand is thus capable of standing upright, without any outside support, when the bottom platform is on a substantially flat underlying ground surface.

An apparatus for a roll battle game comprises discs; disc bases, wherein each of the discs is disposed on each of the disc bases, and wherein each of the discs is relatively rotatable axially to each of the disc bases, and wherein a hole is formed; balls; and obstacles to impede the balls into the holes of the discs, wherein the obstacles are associated with the discs or the balls or both. A method of rolling battle game comprises steps of providing a roll battle game apparatus, introducing the plurality of players, directing players to either roll the ball to the hole or strike the ball of a previous player until all players roll the ball to stay in the hole; permitting players whose ball was struck by the other players to rotate the disc; the first player rolls to the base goal in the final iteration is the winner.

An adjustable dumbbell system may include a handle assembly, at least one weight, at least one sensor, and a computing device. The at least one weight may be selectively fixedly connectable to the handle assembly. The least one sensor may be positioned on the handle assembly. The at least one sensor may be configured to detect a handle assembly attribute indicative of whether the at least one weight is fixedly connected to the handle assembly. The computing device may be in communication with the at least one sensor and may be configured to receive information regarding the handle assembly attribute from the at least one sensor.

The exercising device preferably has a handle with a proximal end and a distal end and a swing arm having a first end and a second end. 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.
