The spherical dynamic resistance device enables simultaneous strength, core and cardiovascular training. A cavity exists whereby resistance bands are stored. By removing a band and connecting it to the exterior of the device at an attachment point and thereafter attaching the other end of the resistance band to a fixed point a user can engaged device to conduct a full body workout. The cavity can also retain a mass element adding weight thereby customizing the weight of the spherical dynamic resistance device. A serpentine channel associated with the outer portion of the device enables a user to grip the device while engaging hand, arm and core muscles. By gripping the device and through various motions that pull opposite of the resistance band while supporting the spherical dynamic resistance device of various weights, a user is able to attain a full body workout.

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 lower 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 is disclosed which is configured to be lifted from a ground surface, comprising 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.

Workout equipment includes a frame and a movable arm pivotally connected to the frame, the movable arm having a first end and a second end. A movable load unit is supported by the movable arm and a load transferer is configured to move the load unit along the movable arm. The movable arm includes a first guide and a second guide, the load unit is supported by the first and second guides and the load transferer includes a locking device for locking the load unit on the first and second guides. The load transferer includes a threaded rod having a first end and a second end, the threaded rod being parallel to the first and second guides. The load unit has a threaded aperture through which the threaded rod projects and the load unit includes weight plates connected together, each weight plate having a hole creating the aperture.

A weight plate that is comprised of multiple parts that connect to each other around the handle of a progressive resistive device.

Provided is a stackable weight that can be stacked alongside other stackable weights to achieve a desired weight on a weight bar. The stackable weight includes a handle to carry the stackable weight, an opening to attach the stackable weight to a weight bar, and at least one feature to engage at least one feature of a second stackable weight. The at least one feature of the stackable weight reduces movement of the stackable weight in relation to any number of other stackable weights when attached on a weight bar. The stackable weights may vary in size and weight to allow a user to achieve a desired weight of the weight bar.

A lot of space and material is typically used to have a full range of exercise weights. An adjustable exercise weight is herein provided to save space and material. The exercise weight, for example, can be dumbbell or a kettlebell or some other type of exercise apparatus. It includes a housing that has opposingly angled inner surfaces. Removable weight pieces are shaped to wedge between the opposingly angled inner surfaces, and the housing supports the weight pieces. A movable holder secures the weight pieces and holds the weight pieces within the housing.

A weighted walker attachment system generally comprises a kit of weighted walker attachments that can be mounted to standard walker or other assistive perambulatory device for use in physical therapy and rehabilitation. A plurality of weighted attachments are provided and adapted to be mounted at a variety of locations on an assistive device. The weight of each attachment can be adjusted, as needed, for example, by adding or removing individual weighted plates mounted on a base plate that itself is removably mounted to the assistive device. In alternate kits, interchangeable weighted attachments can be provided in varying weights, distinguished by optical and/or tactile indicators, and selectively mounted on the assistive device, either as an accessory or in replacing a portion of the device, such as extensions provided on a walker's legs, in accordance with a therapeutic rehabilitation plan for an individual patient.

A weight plate that is comprised of multiple parts that connect to each other around the handle of a progressive resistive device.

A positive pressure airway device for providing resistance in an air pathway for a patient exhaling. The device includes a central tube region, a inspiratory air passageway for passing air into the central tube region when a patient breathing through the device inhales, and an expiratory air passageway for passing air out of the central tube region when a patient breathing through the device exhales, A valve in the expiratory air passageway allows air to flow out only when a patient using the device exhales with an expiratory air pressure greater than a selected pressure, and includes a stopper and a coil spring with an interior portion that is free from any structure that would inhibit the “side-to-side” movement of the spring within the housing. The stopper has a cone-shaped air-stopping surface providing a valve angle that is different from the valve-seat angle so that either laminar or oscillating flow may be obtained.

A set of dumbbells comprises a plurality of dumbbells of different weights with the dumbbells having a common length. A plurality of adder weights is provided with each adder weight having a cavity that is sized to receive the common length of any one of the dumbbells. Any one of the dumbbells is dropped down into the cavity of any one of the adder weights. A slide retainer is then slid into a slideway on the any one adder weight to overlie the dumbbell and secure the dumbbell to the any one adder weight. The slide retainer has a window therein to allow a user to reach through the slide retainer and grip a hand grip of the dumbbell.
