A ball chair may comprise a chair frame, a ball body and an adjusting unit. The chair frame has a connecting base and a legs base, and a supporting column formed therebetween is configured to achieve a telescopic action thereby adjusting a height of the ball chair. The connecting base is formed in a concave shape to form a housing space therein, and an annular frame is formed at an upper end of the connecting base. The ball body is configured to be coupled on the connecting base of the chair frame, and the annular frame is configured to couple with an outer periphery of the ball body thereby limiting a position thereof. As a result, the ball chair is suitable for different statures of users and enables the users to sit thereon for training or rehabilitation.

A chair includes a seat (2) and also includes a pair of thigh support elements (17) pivotal n a generally downwardly direction about front pivot axes (20) from a first state forming with a central seat element (15) a substantially common plane, to a second downwardly extending state. The elements (17) are also pivotal about second pivot axes in a generally rearwardly direction for urging the user's thighs away from each other for stretching the adductor muscles. Foot support members (49) extend transversely and sidewardly on respective opposite sides of the chair (1) from a support element (46) for supporting the foot during a stretching exercise with the corresponding thigh of the subject extending downwardly from the seat (14) and the lower leg extending from the knee in a upwardly inclined direction to the foot support member (49) for stretching the quadriceps and the hip flexor muscles of the subject.

A foldable exercise chair configured with removable resistance bands to allow various exercises to be performed. An embodiment of the exercise chair allows a user to perform a full range of strength-training exercises and then fold the chair to allow for storage in limited space. This embodiment of the exercise chair is also able to be configured to suit a user's exercise routine by allowing for adding, changing, and removing the resistance bands, as well as modifying the bands for various resistance levels.

A vehicle seat assembly includes a seat base, a seat back rotatably connected to the seat base, a seat bottom mounted on the seat base, and at least one of the following mounted to one of the seat base, seat back, and seat bottom: a resistance mechanism structured to exert a biasing force on at least one exercise arm operatively connected to the resistance mechanism; a bicycle seat receptacle structured for detachably mounting a bicycle seat to the seat base; and a docking mechanism structured for detachably mounting a pedal mechanism to the seat base.

A pedal system for tracking use of a cycle style exercise device. The pedal system includes a pedal with a shaft for coupling to the pedal crank of the exercise device and a housing that is rotatable about the shaft. An accelerometer positioned in the housing is configured to provide data about the movement of the pedal to a microcontroller. A wireless communication chip positioned in the housing is used to transmit the data about the movement of the pedal to a remote device via the wireless communication chip. The remote device is programmed to receive, display and track the data about the movement of the pedal.

The chair of the present disclosure balances safety, comfort, ergonomics, numerous desk geometries, a variety of floor surfaces, the physics of cantilevered elements, the height of floor obstacles, and a large range of body types/sizes. It can address the recommendations of ergonomic experts and adds the unique forward footrest/exercise bar for stretching, core workouts, and to increase the variety of ergonomic seating positions. The entire product can fold into a compact light weight package for easy transport and stowage.

A training device or apparatus for improving performance speed. In one embodiment, the training device includes first and second surfaces disposed in an opposing manner and defining a space therebetween. The space can allow at least one body part of an athlete to cyclically travel between the first and second surfaces in a plane that intersects both of the first and second surfaces. The athlete can be supported such that the body part is substantially free from external resistance along a direction of travel within the plane. In this way, repeated movement of a body part can occur between the first and second surfaces without fatiguing muscles due to external resistance, thereby lengthening the duration of the training session. The at least one body part can include the feet of the athlete.

A ball chair may comprise a chair frame, a ball body and an adjusting unit. The chair frame has a connecting base and a legs base, and a supporting column formed therebetween is configured to achieve a telescopic action thereby adjusting a height of the ball chair. The connecting base is formed in a concave shape to form a housing space therein, and an annular frame is formed at an upper end of the connecting base. The ball body is configured to be coupled on the connecting base of the chair frame, and the annular frame is configured to couple with an outer periphery of the ball body thereby limiting a position thereof. As a result, the ball chair is suitable for different statures of users and enables the users to sit thereon for training or rehabilitation.

An exercise device includes an adjustable strap to secure the device to a free standing object, such as a piece of furniture having two sections. The strap includes hook fabric portions and a loop fabric portion to adjust to a desired length to fit within the sections of the furniture. The exercise device also includes oval rings to attach to the strap at ends thereof. Each oval ring includes a bar located in its center to engage the strap. The position of the oval rings is secured against the furniture. Attachments for exercising, such as exercise bands, are attached to the oval rings so that a user operates the exercise device as needed, then disassembles the device for storage or to use elsewhere.

An exercise device includes an elastic cable, a panel, and a spindle coupled to an interior side of the panel. The spindle has a locked state and an unlocked state, the spindle being rotatable in a first direction to wind the elastic cable and being rotatable in a second direction to unwind both ends of the elastic cable when the spindle is in the unlocked state, and the spindle being non-rotatable when the spindle is in the locked state. A first stirrup is coupled to a first end of the elastic cable, and a second stirrup is coupled to a second end of the elastic cable.
