A hand weight includes a chassis including a handle portion configured to be grasped by a user such that a forearm of the user extends along an axis, and a flexible element attached to the chassis. The hand weight can be configured to receive a movable mass, and the flexible element can be configured to at least partially support the movable mass such that the movable mass forms at least part of a sprung mass of a hand weight assembly including the hand weight and the movable mass, the sprung mass configured to move relative to the chassis of the hand weight and deform the flexible element in response to a force in a direction along the axis applied to the handle portion by the user while grasping the handle portion.

A wrist strengthening device includes a first handle, a second handle coupled to the first handle, and a tightening component coupled to the first handle and the second handle. The tightening component is configured to provide resistance to movement of the first handle and the second handle as the first handle is moved in a first direction and the second handle is moved in a second direction, opposite the first direction. The tightening component includes an outer piece, an inner piece, and a male and a female portion. Movement of the male portion toward the female portion causes space between the inner piece and the outer piece to decrease and friction therebetween to concurrently increase.

A workout device that has an arcuate body having first and second ends, and one or more attachment points extending through the body, each attachment point for releasably attaching a load and for releasably attaching an anchor to suspend the workout device.

In one aspect, the invention features a barbell including a first end portion, a second end portion, and a middle portion, where the middle portion is couplable to the first end portion and the second end portion. The middle portion includes a male coupling extending from a first end of the middle portion, the male coupling providing a first coupling mechanism that engages with a corresponding female coupling of the first end portion, and a female coupling providing a second coupling mechanism that engages with a corresponding male coupling of the second end portion.

A free standing fight simulation workout machine has a fight simulation headed/multi-headed, with or without arms, member that is adapted to be used in conjunction with a slip and counter fight simulation apparatus or stand alone apparatus. The fight simulation headed member for a free standing fight simulation workout apparatus has at least one main support structure having a mounting means. The headed member comprises at least one head terminating at an elongated neck. When present, the arms are arranged to extend from or come out of different areas of said head, face and/or neck. Preferably, multiple heads are provided. The headed member includes a top mating mounting portion and the neck bottom includes a bottom mating mounting adapted to mount on bungee cords mounted through mounting means on the workout apparatus. The head or heads and protruding arms provide various angles adapted for a user to punch, knee, and/or do a flying knee.

An exercise board includes a main body and an elastic body configured on an upper surface of the main body. The upper surface of the main body is provided with at least one cavity, the cavity at least includes a first cavity part and a second cavity part, the first cavity part is located above the second cavity part, and a diameter of the first cavity part is less than that of the second cavity part. A lower surface of the elastic body is provided with at least one protrusion connected to the cavity, the protrusion at least includes a first protrusion part and a second protrusion part, the first protrusion part is located above the second protrusion part, and shapes of the first protrusion part and the second protrusion part match with shapes of the first cavity part and second cavity part.

A method of treating elbow tendonitis in a user's arm comprises providing a container having a handle, filling the container with a prescribed volume of water, holding the container by the handle with the arm hanging at the user's side in a starting position defined by an inward facing of the user's palm, thereafter, rotating the container in a first direction until the arm is at a first rotated position defined by an outward facing of the user's palm, holding the arm at the first rotated position for a first hold time of at least six seconds, thereafter, rotating the container in a second direction opposite the first direction, past the starting position, until the arm is at a second rotated position defined by an outward facing of the user's palm, and holding the arm at the second rotated position for a second hold time of at least six seconds.

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 modular fitness system and associated methods of use are disclosed. In at least one embodiment, the system provides a plurality of elongate weighted segments, and a plurality of handle links sized and configured for accommodating a hand of a user. The segments and handle links are removably engagable with one another in series so as to form an exercise structure. Thus, the user is capable of selectively engaging at least one of the segments having a desired weight with at least one of the handle links in order to form an appropriate configuration of the exercise structure for performing one or more desired exercises therewith.

A free standing fight simulation workout machine with a fight simulation multi-headed, multi-abdomen, multi-armed apparatus is adapted to be used in conjunction with a slip and counter fight simulation apparatus or stand alone apparatus. The fight simulation multi-headed, multi-abdomen, multi-armed apparatus includes a multi-headed member having at least one head attached to at least one abdomen and at least one arm having a glove appending member. Preferably, multiple heads are attached to multiple abdomens with multiple arm pairs to provide different punch configurations for the user to strike at. The multi-headed, multi-abdomen, multi-armed provides various angles adapted for a user to punch, knee, and/or do a flying knee.
