Disclosed is a dumbbell of the type commonly found in a fitness center to be used as a weight training device during a weight training or exercise program. The dumbbell includes a gripping handle and a pair of collars fixedly connected to opposites ends of the handle. A series of weight plates having correspondingly different weights are adapted to be detachably connected to each other and to each one of the collars so as to enable a user to selectively and incrementally adjust the gross weight of the dumbbell to conform to his weight training program. Each weight plate carries a lock cartridge having an engagement pin moving therethrough between retracted and extended positions in response to a manual pushing force. In the extended position, the engagement pin of an additional weight plate is received within an engagement pin extension channel of an existing weight plate being carried by the dumbbell, whereby to prevent a disconnection of the additional weight plate from the existing weight plate.

The invention discloses a model training method for cross-domain sentiment analysis based on a convolutional neural network, belongs to the field of cross-domain sentiment classification, and aims tosolve the problem of cross-domain sentiment analysis. The method comprises: S1, preprocessing a text; S2, training a word vector model; S3, performing cross-domain model migration; wherein the step S3is carried out in sequence; a neural network model is trained through a source domain; migrating the trained model. Firstly, a weight value of a convolution kernel in a model is shared, a convolutionkernel weight trained in a source domain is used for extracting corresponding features in a target domain, a small part of data in the target domain is trained again, parameters of a full connectionlayer weight of the previously trained model are adjusted, and the effect is that model migration is conducted on a cross-domain emotion text.

Disclosed is a weight-training machine having an independent power generating function, which may improve the exercising effect, control the weight caused by a solenoid without external power together with keeping a conventional button manner and eliminate a space limitation for installation of the machine. The weight-training machine has an independent power generating function so as to minutely adjust an exercising load without supply of external power. An operation distance between a fixing plate and a push button of a fixing device is minimized to allow one-touch manipulation. The solenoid may be operated with a lower electric energy. Thus, stacks are not shaken in rightleft or front/rear direction on the basis of the fixing plate and the insert groove when a stack selected by the fixing plate and stacks upon the stack are moved up and down at the same time.

A weight training apparatus that simulates free weight lifting exercise. It allows the user to load regular Olympic plates to adjust weight resistance, and thereby eliminate the need to pick-up or replace a dumbbell set each time he wants to adjust the weight resistance. The apparatus comprises a cage like frame and a vertically adjustable table with arm extension supports with a series of handles and weight loadable pin attached to each arm. The arm extensions can swivel, rotate in a circular manner and independently to provide the feel of the unrestrained free motions many free weight lifters prefer when working with regular dumbbells or free weights.

A barbell assembly includes a bar and a weight subassembly adjacent each end of the bar. Each weight subassembly includes a wheel with a predetermined pattern of through holes and an inflatable component around the periphery of the wheel. A hub defines a flange having a plurality of through holes corresponding to the through holes on the wheel for securing the wheel to the hub with fasteners. The hub is secured to the bar with fasteners, or the flange is secured to the bar by welding or with fasteners. An outer end of the bar is provided with a U-shaped swivel having a hook that rotates freely relative to the outer end and the grip portion of the bar. The barbell assembly may be utilized to perform weight training exercises without causing damage to an exercise surface, and may be locked to an immovable fixture using a tether and a lock.

The invention discloses a programmable drag controlling device and method for body-building equipment, which comprises the following parts: controlling unit, driving mechanism and force metering device, wherein the driving mechanism possesses motor and gear box; the coiling cylinder is set in the gear box to coil thread; one force metering device is set among rollers of thread device; the load quantity is input into panel of control unit, which outputs to driving mechanism to make motor move and coil cylinder to rotate to draw or release rope; when the resistance is abnormal, the microprocessor judges whether the signal drives mechanism to stop or release rope or draw back.

A weight training assembly includes a frame includes a first rail to which a slide member and multiple weights are connected. The slide member has a main rod with multiple through hole. Each weight has a transverse holes and longitudinal holes, each transverse hole has a pin received therein, and each longitudinal hole has a push rod received therein. A first spring is located between the pin and the weight. A second spring is located between the push rod and the weight. A push unit includes a push member which is located corresponding to the front sides of the weights. When the push member pushes the push rod from the first position to the second position, the pin moves from the third position to the third position and extends through one through hole to lock the weight to the main rod.

A weight training machine includes a support frame, and a selector. The support frame includes two parallel guide rods, a plurality of weights, and a drive shaft. The selector device includes a selector that is inserted into a gap between any two adjacent weights and connected to the drive shaft, and a reel mounted on the selector and having a retractable pull wire having a distal end secured to the support frame.

A weight training apparatus reconfigurable between an open configuration and a compact configuration in which the apparatus is packed into a smaller form than in the open configuration. The apparatus includes one or more storage compartments configured to removably receive and retain a weighted material to selectively increase the weight of the apparatus. If including more than one storage compartment, each can be movable relative to one other and are shaped and arranged to enable the apparatus to be reconfigured to the compact configuration in a filled condition in which the storage compartments contain weighted material. The apparatus can be configured in the compact configuration without weighted material for transport or storage. The absence of any weighted material makes the apparatus lightweight to carry, as well as enabling it to compact to a much smaller size than in the in-use filled configuration.

The present invention relates to an apparatus for enhancing isometric and/or isotonic exercises and methods of using same. In particular, the apparatus for enhancing isometric exercises includes a substantially rigid annular exercising assembly which is placed in a user's mouth and held in place by the user's lips and more particularly between the user's lips in such a manner that the user's upper and lower teeth are not in a substantially engaged position. The substantially rigid annular exercising assembly has an exterior and an interior wall which connect and thereby form a trough. The anterior, medial and posterior surfaces of the user's lips fit within the trough thereby providing the mechanism for holding the substantially rigid annular exercising assembly within the user's mouth during exercise.

When in place, the substantially rigid annular exercising assembly increases isometric resistance during exercise, weight training, or facial toning. When used as an isotonic exercising aid, the apparatus would be substantially flexible or semi-flexible to thereby allow some movement of a user's jaw and other facial muscles.
