A hand, wrist and forearm exercise device includes a resistive hand grip exerciser disposed at each end of a flexible, elongated resilient member. The flexible, elongated resilient member is arcuately bendable along a longitudinal axis and also one end is twistable relative to the another end along the longitudinal axis.

A portable single biceps exercising machine comprises an articulable framework running about a length of a user's arm. The articulable framework may be divided into an upper framework and a lower framework, with an articulable fulcrum connecting the upper framework to the lower framework. In use, the upper framework, at an under arm pad, may be retained in a shoulder/armpit region of the user's arm, while the lower framework may comprise a handle to be engaged by a hand of the user's arm. One or more tension members are coupled between the upper framework and the lower framework such that articulation of the handle about the articulable fulcrum towards the under arm pad is through a resistance. The resistance exercises a biceps muscle of the user's arm.

An exercise device is described. An exercise device including a body, the body having a top, a bottom, a first end located at one edge of the body, a second end located at an opposite end of the body, and first and second sides extending between the first and second ends; a first axle connected to a first wheel, the first axle also connected to the body proximate the first end at a first hub; a first spring having a first spring end, the first spring positioned at least partially within the first axle, with the first spring end slidably connected to one of the first wheel and the first hub at a first junction, wherein the first junction is configured to convey torque between the one of the first hub and the first wheel and the first spring end.

A device for rehabilitating or strengthening the ankle includes a plank that is connected by a transversely oriented hinge and a longitudinally oriented pivot, as well as a pair of compression springs at its forward end. The connections of the plank to the underlying base limit the plank to motion in two directions about two axes, thereby providing four types of therapeutic ranges of motion, including dorsiflexion and plantar flexion, eversion and inversion. A transversely slidable foot rest enables the user to hold device 21 in position with one foot while using the plank of the device to rehabilitate the other foot.

A preloaded resistance pack and exercise device. The resistance pack includes an elastomeric resistance element coupled to a hub and disposed on a plate. The hub includes a pair of radially extending wings that lie against a surface of the plate. The plate includes a pair of raised tabs that lie within a rotational path of the wings. An initial rotation of the hub relative to the plate causes the wings to slide over and beyond the raised tabs and at least partially stretches the resistance element. Interaction between the tabs and wings prevents the hub from rotating back to an initial position and maintains the resistance element in a preloaded, tensioned condition. The exercise device is configured to detect a number of the resistance packs coupled thereto as well as data associated with exercise movements employing the resistance packs.

An adjustable resistance exercise machine for providing variable resistance forces on a pull cable extending from the machine. The adjustable resistance exercise machine generally includes a plurality of power springs that may be selectively engaged using a cam mechanism. By engaging springs with different forces, the resistance may be adjusted incrementally as preferred for performing different exercises. The adjustable resistance exercise machine may be connected to various structures, either below or above an exerciser, to allow the exerciser to choose whether to pull the pull cable up or down during exercise.

The present invention discloses a multifunctional abdominal exercise wheel, comprising a main body, support members, a central pipe fitting, and a spring barrel. Two ends of the central pipe fitting are each provided with a support rotating member. The support rotating member is pivoted to a support member. The central pipe fitting is inserted into the spring barrel and fixed. The spring barrel is provided with a power spring. The main body is fixedly provided with a single-chip microcomputer, and a display apparatus, a sensor, and a button separately electrically connected to the single-chip microcomputer. Therefore, motion data can be displayed, the stroke and resistance of the abdominal exercise wheel can be adjusted, torsion outputs are stable, and springback noise is small.

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.

An exercise and rehabilitation bar including a flexing bar, at least one resistance insert, and at least one handle. The flexing bar has a first end, a second end, and a cavity running from the first end to the second end. The at least one resistance insert is removably carried within the cavity of the flexing bar and the at least one handle is removably securable to either the first or second end of the flexing bar.

A weighted dumbbell having a housing 4, 34 with a substantially cylindrical envelope in a first configuration, and convertible into an abdominal roller in a second configuration, the dumbbell including two elongate handles 8 located along an axis of said housing, said handles being lodged within the housing 34 in the first configuration and being slidable in mutually opposite directions along the axis, such that in the second configuration the handles 8 extend outwardly from said housing and the housing 4, 34 is rotatable about the axis with respect to the handles.
