An interacting exercise device is revealed. The interacting exercise device includes a driving device and a non-concentric actuator driven by the driving device. While the driving device is operated to rotate, the non-concentric actuator vibrates and the vibration generated is delivered to the interacting exercise device for interacting shaking fitness.

An exercise apparatus is provided. The exercise apparatus includes a substantially round, hollow element having an exterior surface and an interior cavity, with the round, hollow element having a U-shaped cross-section, the U-shape including two distal ends. The exercise apparatus also includes at least two rims, each rim positioned about a portion of the round, hollow element at each distal end of the U-shape. A spacer member is located between each distal end of the U-shape and between the rims and at least two fasteners extend between both of the at least two rims, the fasteners providing a clamping force to the at least two rims so that the spacer member and both distal ends of the round, hollow element are fixed relative to each other.

An adjustable sledgehammer workout apparatus may include a handle, a pair of supporting brackets connected to the handle, and a clamping assembly connected to the supporting brackets. The supporting brackets may be rectangular in shape with beveled or rounded edges. The clamping assembly may include a pair of lower c-shaped portions connected to a pair of upper c-shaped portions using a hinge assembly. Different size and weight dumbbells may be connected to the handle using the clamping assembly.

This disclosure provides an exercise device comprising a weighted head and a handle. In some embodiments, the exercise device may be essentially as shown in FIGS. 1-4.

A multi-purpose home workout device. The device comprises a resistive weight with an open channel designed to allow an axle to pass therethrough, such that the axle is operably connected to a wheel, and an outer frame. The outer frame further includes a pair of bracer arms designed to receive the axle and to redistribute the weight of a user across the outer frame. The wheel includes an open interior space and is positioned between the bracer arms such that the resistive weight can rest on the axle within the interior space. Furthermore, the orientation of the wheel and the outer frame allow both to rotate about the axle without interfering with one another's movement. As such the outer frame is predisposed to tilting at non-horizontal angles when in use, and thereby forces a user to train their balance, strength and coordination simultaneously.

A weight-balanced apparatus, comprising: a main body shaped substantially like a hollow sphere with spherical caps removed in a same central axis of the body to create two opposing openings sized to account for the natural motion of a user's arm during exercise and where the main body is balanced in each of at least three dimensions from a center point of the sphere, wherein each of the two opposing openings have a continuous, rotationally symmetric beveled edge around the opening; and, a hand hold traversing centrally through the hollow of the spherical main body through the center point and transverse to the central axis.

A sport exercise device; for use with a sport stick, the sport stick having a head and a shaft. The device comprises a face, edge and attachment means. In one approach, the edge is adapted and arranged to surround the stick's head. The attachment means allows attachment of the device's face to hold an independently provided weight with respect to the head. The attachment means may allow attachment of the device's face to close the stick's net sufficient to prevent out-passage of a ball within the net.

A jump rope device includes a connection assembly having a male connecting member and a female connecting member. The male connecting member includes a head having at least one locking projection. The female connecting member defines an opening configured to receive at least a portion of the male connecting member into an internal cavity. The female connecting member includes at least one locking arm that is biased into a first position, and configured to move from the first position into a second position when the male connecting member is inserted into the opening. The at least one locking arm is configured to return to the first position following insertion of the male connecting member to thereby create a secure connection between male and female connecting members.

An apparatus and method for exercising with a child attached to the legs is disclosed. An example embodiment includes: a child wrap element having a portion that can be wrapped around and secure a child; a leg wrap portion having at least one loop that can be secured to the legs of a user; and a connecting portion integrated between the child wrap portion and the leg wrap portion.

A rotation exercising ball structure includes two shells, two pivot seats, two holding members, a weight unit, a first housing, a second housing, and a PCB (printed circuit board). The two shells are combined together to construct a hollow ball. The weight unit includes a mandrel pivotally connected with the hollow ball, two magnets secured to the mandrel, at least one rotation member connected with the mandrel, and a weight connected with the at least one rotation member. The PCB is electrically connected with a Bluetooth transmission device which is electrically connected with a Hall sensor. When the mandrel is rotated, the Hall sensor detects rotation of the magnets and sends information of rotation of the magnets to the PCB, and the PCB processes and transmits the information to the Bluetooth transmission device.
