A rowing machine with the volute rotary resetting mechanism is further provided.

There is provided a plank exercise device including a support portion adapted to receive arms or hands of a person and adapted to receive a display device, a destabilizer connected to the support portion, and a stationary base adapted to hold the destabilizer.

An orthotic support comprises a shoulder section for encapsulating a first shoulder of a wearer, a glove section for conforming to at least a portion of the wearer's hand, and a sleeve section for conforming to the wearer's arm, the sleeve section connecting the shoulder section to the glove section. A resilient reinforcement extends from the glove section to the shoulder section, and at least a portion of the reinforcement extends in a spiral around the sleeve section, so that the reinforcement is configured to apply a rotational force to the wearer's arm, when worn, to urge a portion of the wearer's arm to rotate in a predetermined direction. The orthotic support may be usable to treat or prevent shoulder dislocation or subluxation, arm over-pronation or over-supination, wrist flexion or elbow flexion. An orthotic support may comprise a reinforcement with a first branch extending over an anterior portion of the sleeve section, and a second branch extending over a posterior portion of the sleeve section, so that the reinforcement is configured to urge the wearer's upper arm towards a rest position.

Disclosed herein is an exercise machine that includes an elongated frame having a head end and a foot end, and a moveable carriage slidably coupled to the elongated frame and moveable between the head end and the foot end, the moveable carriage having a spring bracket coupled to an underside of the moveable carriage. The exercise machine also includes a spring support rod slideably coupled with the elongated frame and disposed adjacent the foot end, and selectively positionable with reference to the foot end by a handle that extends from an interior area of the elongated frame to an exterior area of the elongated frame. The exercise machine also includes at least one resistive member coupled at a first end with the spring support rod and at a second end with the spring bracket, and configured to bias the moveable carriage towards the foot end of the elongated frame.

An exercise apparatus for assisting a user with a range of exercises includes a frame having a first frame section extending in a generally horizontal direction. At least one carriage is configured to support a user, wherein the carriage is slidably supported on the first frame section. A first resistance system has a first resilient member removably connected to at least one of the carriage and/or the frame. The displacement of the carriage relative to the frame exerts a tensile force on the resilient member. A second resistance system includes a load moveably mounted with respect to the frame and an actuation member connected to the load. The actuation member is configured to displace the load when a force exerted by the user on the actuating member exceeds a predetermined threshold representative of the load.

A shoulder motion exercise device and method of use having a retainer, a connector, an extender, and a slider. When the user mimics a golf swing, the device aids in the stretching and exercise of at least a shoulder and a portion of the torso.

A fitness device is provided, the fitness device comprising: an elastomeric member having an interior cavity, the elastomeric member comprising a cylindrical portion extending between a first hemispherical endcap and a second hemispherical endcap, wherein a surface of the elastomeric member defines an aperture positioned between the interior cavity and an exterior of the elastomeric member; and a structured surface positioned on the surface of the elastomeric member over the aperture, the structured surface extending into the interior cavity of the elastomeric member.

A multipurpose exercise device for replicating exercise motions that has a base on a support surface and a user platform. One end of a support post is axially mounted to the base and the other end is pivotally mounted to the user platform. The platform pivots with the post in a horizontal plane parallel to the support surface and pivots in a vertical plane perpendicular to the support surface. Resistance elements, dampening elements and a linkage system are selectively mounted to the support post and the base to control the velocity and angle of pivot of the platform in the horizontal and vertical plane. Ski and snowboard modules may be mounted to the user platform. The user stands on the platform or modules and performs exercise motions to propel the platform in the horizontal plane and the vertical plane to replicate the exercise motions, e.g., skiing and snowboarding.

An abdominal exercise device includes a frame comprising top, middle, and bottom frame sections. The middle frame section has a curved shape for creating a teeter-totter movement during exercise. The device includes a headrest connected to the bottom frame section, a plurality of connectors for connecting elastic bands to the frame, and an elastic band connected to at least two connectors. The two ends of the elastic band are connected to two straps. The device creates the teeter-totter movement to exercise the abdominal muscles in response to a person lying down in supine position with the back of the head on the headrest and the feet in the two straps, the person applying a downward pressure with the feet to the straps to move the headrest from a resting position, and the person removing the downward pressure to allow the headrest to go back to the resting position.

An exercise machine inclination device for providing variable exercise intensity on an exercise machine by inclining the exercise machine. The exercise machine inclination device generally includes a base adapted for being positioned upon a floor, a support structure adapted for supporting the exercise machine, a hinge pivotally connecting the base and the support structure and an actuator connected between the base and the support structure, wherein the actuator adjusts an angle of the support structure.
