Systems and methods for a small light weight unit that can be securely held and centered in the palm of the holder during physical activities, such as exercises, including aerobic exercises. The weight unit also includes features for securing the weight in the palm during the exercise to achieve a specific desired weight and intensity of workout.

Improved designs for exercise machines that facilitate muscle development and other therapeutics are disclosed. The machine includes a frame, a pulley assembly, and cable extending through the pulley assembly. The cable has attachments, including an attachment for connecting to a pull handle. The cable is also connected to a selectively variable moveable resistance unit. This unit is structured to provide an elastic resistance when a pulling force is applied to the pull handle. The unit is connected to the cable and includes an elastomeric body that provides the elastic resistance and also includes an arc plate that provides a curved support member on which a portion of the elastomeric body at least partially wraps around. Movement of the arc plate causes the elastomeric body to stretch and to provide the elastic resistance.

A training device may include a frame. The frame may include a main shaft having proximal and distal ends; a left mount and a right mount each disposed perpendicular to the main shaft; a weight guard extending radially from the main shaft; a sheath protruding from the main shaft; and a fastener well disposed on the sheath. Further, the training device may include a t-bar. The t-bar may include a support member comprising a plurality of holes. The sheath may be sized to accept the support member. A left rail and a right rail may each be disposed orthogonal to the support member.

Provided is an exercise machine system capable of adjusting a weight by using flow weights, and more particularly, to an exercise machine system capable of adjusting a weight by adjusting the number of flow weights such as short balls and loading the flow weights in a flow weight loading part of an exercise machine. The exercise machine system capable of adjusting a weight by using flow weights, which is capable of allowing a user to perform an exercise with a desired weight by setting up an exercise weight and supplying the flow weight parts to the flow weight loading part based on the preset exercise weight. Therefore, it is possible to eliminate the inconvenience to the user having to manually adjust the weight.

An exercise device includes a shuttle configured to translate along a first and a second cable in response to a separation of the cables by a user. The cables may extend along first and second cable slots that extend through a shuttle housing between first and second sides of the housing. First and second pulleys may be rotatably mounted to the housing and include corresponding first and second engagement surfaces configured to engage respective the first and second cables within the respective first and second cable slots. Separation of the cable ends, proximate to the first side of the housing, relative to the first and second cable slots drives rotation of the pulleys and corresponding translation of the shuttle along the cables, away from the separating cable ends.

A weight plate includes a first section having an annular shape with a passage extending axially through the first section and configured to receive an elongated member therethrough, and a second section having an annular shape and positioned radially outward of the first section, where the second section includes first and second outer surfaces on opposite axial sides of the weight plate with an axial thickness defined between the first and second outer surfaces. The second section has a plurality of recesses each extending axially inward from the first and second outer surfaces at least partially through the axial thickness of the second section.

A four-bar linkage assembly exercise station that can be adjusted to various configurations to create various exercise motions having at least one adjustable operational pivot that is movable prior to operation of the machine and stationary during operation of the machine and at least one stationary adjustment pivot operatively connected to the at least one adjustable operational pivot. The stationary adjustment pivot is also operatively connected to an adjusting and latching component or assembly that can be engaged by a user prior to operation of the machine to adjust the four-bar linkage assembly exercise station to a desired configuration to create a unique exercise motion and secure the desired configuration of the adjustable four-bar linkage assembly.

The invention presented is an aquatic weight training device that enables weight training in an aquatic environment while allowing eccentric weight training. The inventive device includes at least one hollow bar with hollow weights attached at each end. The end weights each include a plurality of holes that allow a user to fill the end weights under water then controllably empty the end weights while exercising. The end weights may be fixedly or releasably attached to the bar.

Described herein are methods of manufacturing multi-use mounting brackets having an extension with an internal support rod configured to support gym accessories. A single multi-use mounting bracket fits gym rigging or gym racks of different sizes and hole configurations. This accomplished by including multiple pairs of holes that are sized and positioned to be compatible with different gym rigging configurations. The multi-use mounting brackets described herein are advantageously designed to resist both downward and upward forces.

A weight stack isolator comprises an impact damper having a rail void therein configured to receive a guide rail of a selectorized machine. The impact damper is shaped to at least partially surround a section of the guide rail when received in the rail void, to secure the weight stack isolator to the selectorized machine. The weight stack isolator may include a slit extending from its outer perimeter to the rail void or the rail void may extend to the outer perimeter, to removably receive the guide rail in the rail void. The weight stack isolator can be positioned under a weight stack of the selectorized machine to absorb or dampen noise and vibration.
