Abstract: A weightlifting apparatus has multiple disc weights. Each disc weight has a round base and a round cover assembled on the round base. The round base has multiple locating slots formed therein. The round cover has multiple locating holes formed therethrough. When the locating slots align with the locating holes, lightweight weight plates or coins can be inserted into corresponding locating slots. When the locating slots misalign with the locating holes, the inserted weight plates or coins can be retained in the locating slots. Accordingly, easy weight adjustment and cost-saving effect can be achieved without requiring users to purchase an entire set of disc weights. With incremental fine weight adjustment of weight plates and coins, users can quickly adapt to the adjusted weight, and the exercise injury caused by large increment of weight adjustment can be avoided.

Abstract: A Halo Posture head weight is comprised of two consecutive rings. A lower ring is hollow and conformal while also being shape-sustaining to fit comfortably around the skull at approximately the level of the forehead. An upper ring has metal shot in the forward half to apply weight load at the frontal section of the head. Both rings have adjustable closures at the back of the head for a comfortable, adjustable, and secure fit. Additional pads are provided for coupling extra weight, to permit correction of tilt or adjustment of weight loading. In a preferred embodiment, the rings are fabricated from a single strip of double-backed neoprene that is formed using two longitudinally extensive stitch lines, and an additional resilient fabric bag is provided for securing the metal shot in the upper ring.

Abstract: A multipurpose exercise machine requiring only three points of adjustment centrally located. It has a one point height adjustment and two adjustments for the rotating arm assemblies.

Abstract: Exercise weight bars are disclosed that provide an easy and efficient way for a user to quickly remove, add, and secure weight plates to the exercise weight bars. The exercise weight bars provide weight locks that may remain attached to the exercise weight bar during the interchange of weight plates. The exercise weight bars can accept one or more weight plates on the ends thereof. The weight locks includes extension members that engage the weight plates when the weight locks are rotated to a locked position, thereby securing the weight plates to the exercise weight bar. When the weight locks are rotated to an unlocked position, the extension members are retracted to disengage the weight plates, thereby allowing the weight plates to be removed from the exercise weight bar.

A horizontal stack of weights is disposed on opposite sides of a base member, and at least one selector rod is movably mounted on the base member and selectively moved into engagement with the desired number of horizontally stacked weights. Various combinations of these arrangements may be used to provide adjustable resistance to exercise on dumbbells and/or weight stack machines.

Abstract: A muscle toning kit includes an exercise garment having a first resistance article and a second resistance article. The first resistance article and the second resistance article cooperate to facilitate the exercise of at least one muscle group of a user. The first resistance article is adjustable to provide a range of user selected resistance levels, while second resistance article has another range of user selected resistance levels so that as the user maneuvers the exercise garment, its adjustable pressure opposing structures facilitate the toning and conditioning of the at least one muscle group of the user. The method includes wearing and deforming the exercise garment from its original shape through natural extension and flexing actions of the user to facilitate providing a resistive force to condition the at least one muscle group of the user.

Abstract: A weighted vest includes a pair of mirror image front panels joined to a back panel to form a sleeveless weight supporting vest. A plurality of pliable easily conformed weight packets are secured within the vest interior by fabric attachment pads together with a combination of elastic bands and belts. The vest provides weight distribution particularly suited to activities of substantial acceleration such as sprint starting, American football or the like. A porous liner and mesh outer layer over certain areas of the vest allow heat to be vented from the vest interior. A pair of variable spring rate expansion joints are coupled between the front panels and the back panel passing over the shoulder, neck and collar bone region of the athlete's body to provide reduction of localized stress upon the athlete.

Abstract: An apparatus that facilitates the stretching and exercising of the hamstring and back muscles is provided. The apparatus can be used for stretching to improve flexibility, to warm up muscles before physical activity, and/or for physical rehabilitation after injury. The apparatus includes a set of hand grips and a set of foot plates. A user grasps the hand grips and positions the arches of his or her feet above the foot plates. The apparatus includes a user actuated drive mechanism for moving a set of hand grips along the shaft toward the foot plates. The user maintains a grip of the hand grips as the hand grips move along the shaft toward the foot plates, thereby stretching the hamstring and back muscles of the user.

Abstract: An exercise device with an arc shaped track having a concave side that is mounted upon a support structure that supports the arc shaped track at a position in which the concave side of the arc faces downward and in which the arc shaped track can be fixed at a location centered above a user's head to extend to each side of the user. When in use, a track follower engages the track and moves along a length of the track to follow a course defined by the arc shape of the track. A handle is coupled to the track follower to be gripped by the user's hand to guide the user's side to side bends. This abstract is not to be considered limiting, since other embodiments may deviate from the features described in this abstract.

Abstract: A device for generating power from a locomotion energy associated with leg muscles acting across an ankle joint. The device including: a cuff worn on the leg; a shoe; an energy absorbing element operatively connected to the cuff and shoe for absorbing energy during one or more periods of a periodic motion of the joint in which energy is absorbed by the muscles.

Abstract: An abdominal training apparatus provides focused training on the abdominal muscles using a resistance provided by a resistance device. The user may be supported in an elevated position by a seat support. A cable may transfer the resistance from the resistance device to the user. One or more pulleys may guide the resistance such to the user such that a force vector below and away from the user is provided to the user. In use, the user may perform abdominal training by engaging or grasping the cable to engage the resistance. The user may also support or secure one or both legs using a leg support of the apparatus. The force vector of the resistance is highly beneficial in that it allows the resistance to target and strengthen the abdominal muscles.

Abstract: A jump rope simulator for aerobic and anaerobic exercise having a hand-held unit comprising a handle, a base length connected to the handle, and one or more concatenated extension lengths attached to the base length. To exercise, the user grasps one or two units, imitates the motions of swinging a conventional jump rope, and jumps up and down, but there is no risk to the user of tripping over a rope as with a conventional jump rope. If the user desires, two units may also be linked together with an easily attachable connector to form a device similar to a conventional jump rope. A user can quickly convert between the two configurations of the jump rope simulator.
