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

The invention presented is an aquatic weight training device that enables weight training in an aquatic environment while allowing eccentric weight training. The inventive device includes at least one hollow bar with hollow weights attached at each end. The end weights each include a plurality of holes that allow a user to fill the end weights under water then controllably empty the end weights while exercising. The end weights may be fixedly or releasably attached to the bar.

An aqua resistance dumbbell comprises a tubular wall that provides a bore for receiving a user's hand from each end of the bell. A rod is located within the bore and extending laterally across the bore to be gripped by a user with one or both hands from one or both ends of the bore. The dumbbell has a plurality of longitudinal fins extend along the tubular wall on an outer side of the tubular wall, and at least one lateral fin that extends laterally at least part way around the tubular wall. An aqua resistance fin assembly comprises two fin components and at least one fastening member for fitting the fin components to a user's limb in a side-by-side configuration around the limb. Each fin component comprises a base adapted to fit against a user's limb and adapted to be secured to the user's limb by the fastening member, and at least two longitudinal fins and at least one lateral fin on an outer side of the base.

A rowing machine has a base, a seat, a rotating plate, two oar components, a damping mechanism and a transmission mechanism; the base with a rack and a slope rail; the seat cushion slidably coupled to the rail; the rotating plate with a fixing rotating shaft rotatably assembled to the rack through the rotating shaft; two oar components respectively connected to the two ends of the rotating shaft by unilateral bearings in universal joining way to unilaterally drive the rotating plate to rotate when swinging; the rotation damping mechanism is assembled to the rack; the transmission mechanism assembled between the rotating plate and the damping mechanism to drive a damping wheel of the damping mechanism when the rotating plate rotates.

A Pilates Aquatics Device (PAD) including a board, the board being generally rectangular, planar, buoyant, and having top and bottom surfaces, first and second sides that are generally parallel to one another with a longitudinal axis midway there between, first and second ends generally perpendicular to the longitudinal axis, and a strap defining three loops on the top surface of the board, the loops aligned along the axis, the loops defining openings perpendicular to the axis for insertion of a user's hands or feet to control the PAD.

A swimming machine comprising a housing adapted to be mounted to an interior wall of a swimming pool. The housing comprising a hydraulic motor connected to an impellor mounted within the housing for producing a current of water in the pool when in use. The swimming machine further comprising a hydraulic pump stored outside the housing operably connected to the hydraulic motor mounted within the housing, an electric motor connected to and powering the hydraulic pump, an inverter drive system connected to, powering and controlling the electric motor. Wherein in use the speed of the current produced is controlled by the inverter drive system.

A hand-held exercise device comprises a frame, a handle attached to the frame, a spool element pivotally mounted to the frame, a pull-cord movable between a wound configuration in which the pull-cord is wound around the spool element and an unwound configuration in which the pull-cord is unwound from the spool element, a resistance element pivotally mounted to the frame, a transmission that couples the pull-cord to the resistance element such that pulling the pull-cord from the device causes the resistance element to rotate, and a damping means that acts to slow the rotation of the resistance element. The device provides a compact and lightweight form of exercise equipment that is easy to carry and easy to store. The device can be used with various fixtures, and also with a second handle fixed to the pull-cord, to allow the user to perform a wide range of exercises. Preferably the exercise device transmits exercise data to an external device that provides feedback and guidance to the user. A resistance mechanism for exercise apparatus allows a pull-cord to be coupled to a resistance element such that pulling the pull-cord from the mechanism causes the resistance element to rotate. A drive element is driven by a frictional force between the drive element and the pull-cord. The resistance element is coupled to the drive element by a transmission.

A pool structure uses an installation to receive a treadmill within the pool. The installation has a pan which is embedded within the floor of the pool. A duct projects from the pan through a sidewall of the pool. A motor uses a mechanical transmission extending through the sidewall to provide motive power to the treadmill. Anchoring studs, which are drilled into the pool floor, are attached to the pan via a structural angle weldment.
