A training apparatus for baseball training includes a base and training attachments that may be attached to the base to allow a user to practice a variety of training techniques. The base may be modular so that it has an adjustable width and disassembles into separate components. At least one training attachment is designed to train a batter to properly incorporate thrust into a swinging motion when swinging a baseball bat. The attachment has a pivotally mounted member with a contact element attached to the top end of the member. The member pivots forward and downward when the user's knee contacts the contact element when properly executing a swinging motion. Thus, the training attachment provides direct and immediate feedback to the user regarding the user's batting form. Other training attachments may be used for hitting balls and for pitching to targets strategically placed around a strike zone.

A multifunctional chair is provided. The multifunctional chair includes a supporting body, a telescopic structure, a seat body, and a pedal assembly. The pedal assembly includes a fixing rod, a movable rod, an operation portion, and an elastic resistance member. The telescopic structure is connected to the supporting body and configured to be operated to telescopically move relative to the supporting body. One end of the fixing rod is fixed to the supporting body. The movable rod is movably connected to the fixing rod. The operation portion is arranged at an end of the movable rod away from the fixing rod. Two ends of the elastic resistance member are respectively connected to the supporting body and the fixing rod. A user can push against the operation portion to rotate the movable rod and the fixing rod toward the ground, and the elastic resistance member provides an elastic resistance.

This technology relates generally methods of making and using systems designed to enhance athletic skill development and, more particularly, to methods of maintaining proper foot alignment for certain activities that require agility and consistency. There exists a need for a training device that not only allows a user to dynamically transition back-and-forth between a wider and narrower stance, but also protects the lower extremities of the user when in a narrower stance. In particular, during the process of bringing their legs together, the user's foot and ankle could be injured if the training device is not designed in such a way to ergonomically accommodate the ankle and/or have appropriate cushioning features to insulate the foot and/or ankle from full impact against blunt or sharp surfaces.

An Internet of Thing (IoT) sport device includes a body with a processor, a camera and a wireless transceiver coupled to the processor.

A golf training aid comprising a flexible arm band adapted to releasably fasten, a flexible strip having a first end and a second end and at the first end and the second end a closed loop is formed, wherein at substantially the midpoint of the flexible strip is attached to the flexible arm band, a first band detachably attached to the flexible strip through the closed loop at the first end, a second band is detachably attached to the flexible strip through the closed loop at the second end, and a securing mechanism attached to the second end of the first band and the second end of the second end by the detachable connects, and the securing mechanism is designed to secure to a golfer's clothing.

An exercise machine monitoring and instruction system for the movement of an element of an exercise machine by an exerciser and providing automated feedback to the exerciser to help improve the exercise in real-time. The exercise machine monitoring and instruction system generally includes an exercise machine having a movable element that moves between a first position and a second position in a reciprocating manner, a sensor that detects a real-time position of the movable element, a processor in communication with the sensor to receive the real-time position data from the sensor related to a position of the movable element and a feedback device in communication with the processor that provides real-time instructions to the exerciser on how to adjust their workout to achieve a desired result.

An exercising device including a lever or power arm which is able to be arranged by a first end on a retaining element at a first articulated joint in a way pivotable about a pivot axis or pin, whereby a resistance element is able to be coupled by a first end region at a first coupling point on the power arm, and by a second end region at a second coupling point at a second articulated joint on the retaining element. The exercising device is able to be detachably arranged on a structure by means of an engaging connection, which is formed by a hook-shaped recess and a rod-shaped element and whereby the exercising device is lockable in an engaged position by means of a fixation.

In a first aspect, a method for monitoring a golf swing is provided that includes coupling a mobile telephone to a golf club and employing the mobile telephone coupled to the golf club to monitor acceleration of the mobile telephone as the mobile telephone swings while a user swings the golf club, collect acceleration information based on the monitored acceleration of the mobile telephone as the mobile telephone swings, analyze the collected acceleration information to determine one or more characteristics of the golf swing based on the collected acceleration information, and output information regarding the one or more characteristics of the golf swing on the display of the mobile telephone. Numerous other aspects are provided.

An exercise machine may include a frame, a resistance mechanism supported by the frame, first and second pull cables supported by the frame and linked to the resistance mechanism, a power rack attached to the frame, first and second handles selectively attachable to the first and second pull cable, and first and second pulleys. The power rack includes upright posts configured to have barbell holders adjustably attached thereto such that the barbell holders are configured to be adjusted in various positions between highest positions and lowest positions on the upright posts. The pulleys are configured to selectively receive the pull cables to enable the pull cables to be selectively attached to a barbell to assist or hinder a user in lifting the barbell in a combined cableand free weight workout, the pull cables decoupled from the pulleys for cable workouts.

A variable resistance exercise device is provided that comprises a pair of arm bands and a handle tube that has a longitudinal interior bore. The tube has first and second ends and includes a solid metal center shaft fitted through the interior bore thereby exposing respective first and second end portions of the shaft at the respective first and second ends of the tube. The first and second band arm of the pair of bands arms are respectively fitted onto the first and second ends of the shaft. In some instances, the device is part of a kit that includes a base having a bottom face, where the bottom face includes a groove, and one or more elastic bands, each such band configured to removably couple the base to the exercise bar by fitting the into the groove of the base and through the first and second arm bands.
