A heavy duty, repairable weighted ball used for exercising capable of being loaded to heavy weights and being used on uneven or rough surfaces. The shell of the ball being constructed by a plurality of pieces of material in two layers: an inner encompassing layer capable of holding the weighted material and an outer layer holding the inner layer together. The pieces are joined together such that on being damaged they can be replaced individually. The pieces can be composed of a variety of materials, including repurposed or recycled material.

The device is a modular exercise weight system comprising at least one outer containing bag which can contain at least one particle filled weight bags. The user lifts the outer containing bag for exercise. Multiple outer containing bags may be affixed to a bar and the bar may be lifted for exercise. The outer containing bags may be affixed to an element of a machine and the element of the machine may be lifted or manipulated for exercise.

Systems and methods are provided for testing the ability of an individual to lift objects under various conditions. During standard lifting tests, the average acceleration and velocity of each lift, as well as the distribution of force between the hands and feet of the patient, are electronically measured and recorded. These objective factors can then be used to determine whether the patient is exerting maximal effort, and to assess a patient's condition and progress during a rehabilitation program. In example embodiments, one or more components of the system are adjustable so as to accommodate users of various posture, mechanics, size and movement capabilities.

This disclosure describes a training bag apparatus including weights of the apparatus, one or more fixed and removable components. The training bag is adaptable for exercises wherein one or more fixed and removable elements is utilized as a slam bag, sled, backpack, weighted vest with adjustable internal weights to utilize individually or as an entire training system. The fixed and removable elements comprise of grips, adjustable straps, draggable surface, backpack straps, harness, connecting straps, adjustable internal straps with internal filler weights to use individually and/or as a complete set.

An exercise kit includes an outer bag having a cover and a cavity therein configured to receive one or more removable weights therein. The outer bag has a plurality of spaced apart handles positioned in one or more directions along the outer bag, allowing the bag to be used in one more different exercises. The kit includes a plurality of weight bags, which are fillable by a user to form the removable weights. The weight bags have a closure mechanism having connectable ends that each extend beyond the length of the opening of the weight bag, such that when the inner bags are each filled to a fill level indicative of a selected weight, the opening can be folded over, the bag compressed to remove excess air, and the opening rolled down to the filling. The connectable ends are then connected to form an integral handle portion of the removable weight.

A fitness device for strength training can include: a clamshell housing including a front portion and a back portion. The front portion and the back portion can mate together to define an internal volume. The clamshell housing includes first handle portions extending circumferentially around the front portion and second handle portions extending circumferentially around the back portion. The first and second handle portions mate together to define a plurality of handles. The fitness device includes a sealed container defining a fluid chamber. The sealed container can be fixedly received within the internal volume defined by the front portion and the back portion of the clamshell housing. The fluid chamber of the sealed container can contain: a gaseous component, a first fluid component, and a second fluid component.

A barbell rack includes first and second support members arranged for supporting one end of a barbell, first and second foot members with first and second holder parts fixedly attached to respective foot member and which are arranged for tilting the first and second support members within the respective holder part. The barbell rack further includes first and second eccentric each pivotably arranged at the respective holder part and hingedly connected to a respective bracket which respective bracket is fixedly attached to the respective support member for the tilting of the same within the respective holder part.

A weight lifting apparatus including a generally rectangular beam and two handles arranged near its ends. Each apparatus is designed to provide a more equal distribution of heavier weight across the length of the apparatus. Apparatuses may be connected to one another through locking mechanisms. A weight lifting system includes a series of weight lifting apparatuses of varying lengths and weights and is designed to gradually increase a minimum-to-maximum amount of weight. The series of apparatus gives the user a compact, functional weight increment (a gradual increase in weight for muscular strengthening), with comfortable management during the increase in weight, which is useful for a range of bodyweight motions; standing, sitting, bending, and/or on the ground. The weight lifting system also includes a base with handles and a series of additional beams that can be secured to the base to add incremental weights.

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. In one embodiment, the number of sand training bags with at least one attachable perimeter removably attached to another sand training bag is unlimited.
