An exercise apparatus includes at least one resilient member; a first weight connected to a first end portion of the at least one resilient member; a second weight connected to a second end portion of the at least one resilient member, and a holding member connected to a center portion of the at least one resilient member, the center portion being between the first and second end portions. Another exercise apparatus includes a holding member; a first resilient member having first and second end portions, the first end portion being connected to the holding member; a first weight connected to the first resilient member; a second resilient member having first and second end portions, the first end portion being connected to the holding member opposite the first end portion of the first resilient member; a second weight connected to the second resilient member.

There is contemplated a material covering for a kettlebell which changes the weight of the kettlebell when attached thereon. The material covering in an example may include a generally elongated, fabric wrap. The fabric wrap is secureable around the exterior surface of the kettlebell. The fabric wrap is weighted so as to change the overall weight of the kettlebell. The material covering further may include a securing mechanism attached to the material wrap.

A fitness training bag is provided and includes a body having a first interior volume therein that houses a bladder disposed within the first interior volume. The bladder defines a second interior volume therein that houses a fluid disposed within the second interior volume. A handle is coupled to the body and is configured to facilitate manipulation of the body to perform an exercise. An outer bag for a fitness bag and a fitness training bag system are also provided.

A soft, silent barbell or dumbbell plate designed for low cost fabrication, shipping and sales. It incorporates a leak proof seal to ensure the sand, steel shot or other filler will not come out of the plate during use. It is adjustable in weight and with its durable outer shell, will not mark or chip floors. Since the plate's outer surface is flexible and the general geometric circular plate configuration may deform slightly, the plate is substantially silent in use and when contacting similar plates and the floor.

An exercise device including an outer portion and an inner portion positioned within the outer portion. The inner and outer portions are attached together at a wrist portion in a fluid sealed manner to form a fluid tight cavity between the inner and outer portions. The inner and outer portions are be shaped and sized to provide at least one fluid flow channel or path extending from the wrist portion to a finger portion to allow fluid to flow from the wrist portion to the finger portion and back again, when a user is conducting reciprocating exercises and the fluid cavity is at least partially filled with fluid.

A sand training bag for sand and/or mineral training in an open and closed configuration. The sand pit training bags includes a sand pit training bag configuration comprising at least one fastener and at least one overlaying fabric around the perimeter to open flat on a surface. The sand training bag includes attachable wall structure, wherein the surface attachable wall structure is configured with a sand pit training bag in an open configuration visible relative to a sand or mineral pit held by one or more fasteners. The sand training bag includes a single sand pit training bag, wherein the single sand pit training bag is convertible to a single sand pit with at least one attachable perimeter wall around the perimeter of the open sand or mineral receiving surface configuration, wherein a top cover is configured to be viewed as a sand or mineral pit closed configuration.

An embodiment of the present disclosure of an exercise bag system that includes a bag article, a first closure system, a second closure system and a third closure system. The bag article includes a bottom, a top spaced from the bottom, an opening at the top, and at least first and second side panels that extend from the bottom to the top and defines an internal space such that the opening provides access to the internal space. Each of the first and second side panels have an inner surface that at least partially defines the internal space and an outer surface. The first closure system is at the top and proximate the opening and inside the bag article. The second closure system is at the top and located entirely on the outer surface of the first side panel. The third closure system is at the top and on a foldable panel coupled to the first side panel, such that when the first closure system and the second closure system are engaged, the third closure system is configured to be engaged to seal the bag article.

A fitness training bag is provided and includes a body having a first interior volume therein that houses a bladder disposed within the first interior volume. The bladder defines a second interior volume therein that houses a fluid disposed within the second interior volume. A handle is coupled to the body and is configured to facilitate manipulation of the body to perform an exercise. An outer bag for a fitness bag and a fitness training bag system are also provided.

Weighted apparel designed for training and/or weight loss, for example, along with related manufacturing methods. In some embodiments, a plurality of spherical weighted elements may be positioned within one or more tunnels formed within a piece of fabric. The tunnels may be sealed such that the weighted elements are contained within the tunnels and add a desired amount of weight to the fabric according to the number of weighted elements and the density of the material of such weighted elements. The fabric may be incorporated into a piece of apparel, such as shirts, pants, hats, belts, gloves, socks, ankle or wrist bands, shin guards, or full body suits, for example.

A shell assembly configured for holding one or more weighted articles includes an outer shell having an outer surface and an inner surface defining a cavity configured for receiving the article(s) therein, with an opening providing access to the cavity, a closure configured for selectively opening and closing the opening, and a securing structure configured for securing the article(s) within the cavity to limit movement of the article(s). The securing structure includes a plurality of adjustable straps each connected to the inner surface of the outer shell at a first securing point and a second securing point on opposite sides of the opening. Each of the straps is adjustable with respect to the outer shell to increase or decrease an effective length of the respective strap between the respective securing points, to increase or decrease a distance between the respective securing points and thereby constrict or expand the outer shell.
