Systems and methods for reducing injury sustained during weightlifting and for making deadlifting more comfortable by encouraging correct form with reduced risk of injury. Specifically, this disclosure relates to systems and methods for reducing injury during a deadlift by providing a cushioned, free-spinning roller protective device on an associated barbell which roller is configured to roll relative to the barbell so that contact between the roller and the users leg results in the barbell bar rolling along the leg.

A weightlifting machine that includes a pulley system and a cable system that attaches to a weight rack frame to allow a user to perform a weightlifting exercise. The pulley system may include a first pulley and a second pulley where the cable system engages each pulley. The cable system may have a first end connected to a grip attachment and a second end attached to a resistance element. The resistance element may include a resistance band, a weight support that holds a weight plate, a set of weight plates, or other type of resistance element. The cable system may extend from the pulley through an opening located one of the frame members that form the frame.

A device for exercising upper leg portions and hips which includes a frame, an arm pivotably connected to the frame, and a leg pad pivotably connected to the arm and configured to contact the user's leg during use. The frame having an arm strut and a seat strut. The seat strut having a seat location fixing unit defined by a seat location fixing rod and a seat location fixing place. The seat location fixing place is connected to the frame having laterally spaced apart vertical holes therein for insertion of the seat location fixing rod which attaches to an underside of the seat and is configured as a support post between the seat and the holes within the seat location fixing place. The holes are configured for the user to locate said seat location fixing rod at varying distances and locations from the arm strut.

An exercise bike includes a frame, a rotor assembly and a drive assembly mounted on the frame, where the drive assembly is configured to drive rotation of the rotor assembly, and a cover configured to at least partially cover the rotor assembly. The components of the drive assembly and the rotor assembly include structures that improve the performance of the exercise bike, including but not limited to a strong and rigid construction and improvements in belt tracking, user feel, effort consistency, synchronization, and rotor performance.

The invention relates to a control device for controlling an engine driven transport apparatus. The control device comprises a fitness apparatus having a base part and at least one movable part movable with respect to the base part for enabling a user to perform a physical exercise. The control device further comprises a sensor device for sensing a degree of physical exercise. The control device is arranged for controlling engine power of an engine of the transport apparatus at least partly based on the sensed degree of physical exercise. The fitness apparatus comprises a flywheel rotatably connected to the base part. The fitness apparatus is arranged for setting the flywheel into motion by means of at least one of the one or multiple movable parts. The sensor device is arranged to sense the degree of performed physical exercise at least partly by sensing a degree of motion of the flywheel.

Disclosed is a multifunctional exercise chair for body stretching, comprising a wheelchair frame body, wherein a mounting frame is detachably mounted on an end of the wheelchair frame body away from the driving rear wheel and located under the seat cushion, a pedal gear is rotatably mounted at a bottom of the mounting frame and a pedal is provided thereon, a hand crank gear is rotatably mounted on a top of the mounting frame and a hand crank handle is provided thereon, a rotating shaft is provided between two driving rear wheels; a driven gear is fixedly mounted on the rotating shaft, a supporting chain gear is mounted on the mounting frame and arranged adjacent to the pedal gear, and the hand crank gear, the pedal gear, the driven gear and the supporting chain gear are wound and connected by a transmission chain.

A luminous safety ball including an inner glowing body and a foam sphere covering the inner glowing body is provided. The inner glowing body is not a perfect sphere, the foam sphere has a non-uniform thickness, and light emitted by the inner glowing body passes through the foam sphere and permeates through a surface of the foam sphere to form light with different brightness thereon.

A spacer apparatus for maximizing a user's range of motion on a weightlifting exercise machine. The spacer apparatus includes a first interlocking part having a semi-circular body extending between top and bottom portions, and a lock portion extending between first and second ends of the semi-circular body. The first and second ends are spaced and a keyway is between the first and second ends. The spacer apparatus includes a second interlocking part having a body extending, at least partially, between first and second ends, and entirely between top and bottom portions. The body of the second interlocking part has a semi-circular portion with a key portion extending therefrom. In the interlocked configuration, the key portion extends between the keyway such that an outer perimeter of the first interlocking part and an outer perimeter of the second interlocking part are aligned.

A rigging system is configured for selective attachment to a fixed-point mount (e.g., a beam, a bar, or a door jamb), typically located at a position above the user's head. A handle on the opposite end of the rigging system hangs from this fixed point and is grasped by the user to support a portion of the user's weight while the user performs resistance exercises against a reduced portion of the user's body weight. In some configurations, the fixed point may be a doorjamb above the top of a door. A height adjustment buckle of the rigging system is designed to be positioned generally distal from a structure forming the handle during use of the rigging system.

A mobile device and system which simulates human motion. The device includes a base with a drive system for providing motion to the device. A receiver is provided which controls the drive system the receiver receives wireless control signals. Pads and a self-stabilizing component are provided on the device. The device accurately mimics the unpredictable motion of a human motion to provide a safer alternative to live interaction to increase participant safety and decrease the incidence of injuries during practice or drill sessions. The system includes at least one mobile device. The mobile device includes: a base having a drive system for providing motion to the device; a receiver which controls the drive system the receiver receives wireless control signals; and self-stabilizing component provided on the device. The system also includes a transmitter for transmitting the control signals to the receiver.
