The invention is an external apparatus for the addition of weight(s) to dumbbells and barbells. The external apparatus allows micro-incremental loading between 1.25 to 3.75 pounds on all types of dumbbells and barbells. The device is able to improve trainer and the trainee's ability to break plateaus and to maintain consistent weight progression. The use of this device promotes and stimulates the muscle growth of the user while training. The main advantage of the present invention that women get the significant benefit from this piece of equipment, however, men and women of all body types would benefit greatly from this device.

A pole vault swing-up rack includes a frame body with upper hooks and a lower push bracket. The rack is designed to hang vertically from a horizontal bar—as a pull-up bar—by the hooks. An athlete hanging from the pull-up bar in an upright vertical position may kick his/her legs and torso up to an inverted vertical position to simulate movement of a pole vault. The athlete's shoulders rest against vertical uprights of the rack to maintain the athlete's shoulders and body in front of a vertical plane as in a pole vault movement. A trainer can use the lower push bracket to assist the athlete in the kicking motion. The parts of the rack that come into contact with the athlete may be covered in foam padding and a rubber coating.

An improved exercise assembly structured to be struck by a user includes a base supporting a shaft on a supporting surface. A support shaft extends outwardly from the supporting surface. At least one rotating targets is connected to the support shaft and extends outwardly. A resistance assembly is adjustably mounted on the shaft into and out of a position relative to a path of travel of at least one rotating target. The position includes the resistance assembly in engagement with at least one rotating target. The rotating target includes an elongated arm including a predetermined weighted construction and a safety portion thereon.

Dropping a weight onto a weight lifting drop bag allows a weight lifter to drop a weight onto a floor with minimal damage to the floor, with minimal noise, and without any bouncing of the weight. The bag is a flexible enclosure filled with resilient pellets. The bag has a generally flat or slightly concave upper surface, a length of about two to eight feet, a width of about one and one-half to four feet, and a height of about two to twelve inches.

A multi-layered composite for performing cardiovascular/pulmonary training comprising a first core layer, the upper surface of which is adapted for frictional contact with a body part of a user of the composite and a lower surface affixed to a second layer adapted for frictional contact with a floor of a venue occupied by the user, and a kit and method of performing cardiovascular/pulmonary conditioning.

A mobile device and system which simulates human motion. The device includes a base with a drive system for providing motion to the device. A receiver is provided which controls the drive system the receiver receives wireless control signals. Pads and a self-stabilizing component are provided on the device. The device accurately mimics the unpredictable motion of a human motion to provide a safer alternative to live interaction to increase participant safety and decrease the incidence of injuries during practice or drill sessions. The system includes at least one mobile device. The mobile device includes: a base having a drive system for providing motion to the device; a receiver which controls the drive system the receiver receives wireless control signals; and self-stabilizing component provided on the device. The system also includes a transmitter for transmitting the control signals to the receiver.

A wrist exerciser includes a housing and a gyroscopic member. The housing includes a first cover, a second cover, a supporting portion and a protective assembly. The supporting portion and the protective assembly are disposed between the first cover and the second cover. Two ends of the supporting portion that are opposite to each other are in contact with the first cover and the second cover, respectively. A stiffness of the supporting portion is greater than a stiffness of the protective assembly. The protective assembly includes a rail and a buffer portion that are corresponding to each other. The gyroscopic member includes a ring and a rotor. The ring is slidably disposed on the rail. The rotor includes a ball disposed in the housing and a shaft which penetrates the ball. Two ends of the shaft that are opposite to each other are pivotally connected to the ring.

A barbell includes a bar, a first sleeve assembly having a first sleeve with a first proximal bore portion, a first distal bore portion, and a first central bore portion extending therebetween. An inner proximal bushing is received in the first proximal bore portion, a proximal bearing received in the first proximal bore portion and having two sets of roller bodies positioned between inner and outer races. An outer proximal bushing is received in the first proximal bore portion. The outer proximal bushing engages the first sleeve and the outer race. The outer surface of the inner race has a first annular channel receiving the first set of roller bodies and a second annular channel receiving the second set of roller bodies, and the inner surface of the outer race has a concavely curved annular channel receiving both sets of roller bodies.

A trampoline comprising a trampoline mat defining a jumping area and supported via springs from a circumextending support structure, the support structure including a plurality of legs so that the trampoline mat is positioned at a height above ground or flooring; the trampoline being provided with a safety enclosure surrounding the jumping area. The safety enclosure comprises a net supported by a plurality of telescopically extendable poles, each pole when extended comprising a plurality of sections, each successive extended section with distance above the trampoline mat having a cross-section less than that that of the next less extended section whereby the sections nest when telescopically collapsed. The lowermost such section is supported at a position above the ground or flooring by the support structure.

A weight object configured to be lifted from a ground surface includes a first portion made of high-durometer material, a second portion made of elastomeric material having equal to or durometer than the first portion, and a handle for holding the weight object and lifting the object from the ground surface, where the second portion includes spaced holes within the elastomeric material for absorbing noise generated when the weight object is dropped on the ground surface. Alternatively, a weight object which is configured to be lifted from a ground surface, including at least one layer of elastomeric material having spaced holes therein for absorbing noise generated when the weight object is dropped on the ground surface, and an opening configured to receive a handle.
