    摘要: A method includes: determining a mass of a golf shaft having a length; determining a center of mass of the golf shaft; determining one or more characteristics of an insert based on: the mass of the golf shaft; and a target mass for golf shafts having the length; determining a location of the insert between a first end of the golf shaft where a golf grip is to be attached and a second end of the golf shaft where a golf club head is to be attached based on: the center of mass of the golf shaft; and a target center of mass for golf shafts having the length; and inserting an insert having the determined one or more characteristics within an interior of the golf shaft at the determined location, thereby creating an interference fit between the insert and the interior of the golf shaft.

    摘要: An upper posterior development device is shown and described. The upper posterior development device includes a frame. The frame is created by a plurality of legs. The legs may be secured to one another at a bottom end for additional support. A bench is secured to the upper end of at least one of the plurality of legs. The bench may be rotatably secured to the frame such that the angle of the bench is adjustable. In this instance the bench is secured at least one different leg of the plurality of legs via an adjustment device. A pendulum movably secured to an underside of the bench. The pendulum is configured to have weight added or removed therefrom.

    摘要: Aspects of the disclosure relate to yoga mats. In one example, a yoga mat preserver is disclosed, which includes a perimeter with dimensions substantially similar to a yoga mat, and a thickness substantially less than a thickness of the yoga mat. For this example, at least one component of the yoga mat preserver comprises a moisture absorbent material. In another example, a yoga mat carrier is disclosed, which includes a first end configured to wrap around a circumference of a first end of a rolled yoga mat, and a second end configured to wrap around a circumference of a second end of the rolled yoga mat. The yoga mat carrier further includes a strap in which a first end is attached to the first end of the yoga mat carrier, and a second end is attached to the second end of the yoga mat carrier.

    摘要: A bicycle trainer includes an electric treadmill, a controller, and a sensing unit. The electric treadmill includes an endless conveyor belt on which a user may ride a bicycle. The controller is used to control a running speed of the endless conveyor belt. The sensing unit includes a swinging member and a sensor electrically connected with the controller for sensing a swing of the swinging member and sending a corresponding signal in responsive to the swing. The swinging member is disposed across the electric treadmill and swingable back and forth relative to the electric treadmill, such that the swinging member is pushable by a bicycle wheel to swing. The controller adjusts the running speed of the endless conveyor belt based on the corresponding signal. As such, the endless conveyor belt can match the instant riding speed of the user, thereby providing good riding training and experience.
