An exercise machine. The exercise machine includes a frame, a foot engagement surface operably connected to the frame, and an arm rotatably connected to the frame at a pivot. The arm includes a handle connected to the arm at a first location distal to the pivot. The handle is configured to be gripped by a user. The arm includes a weight receiver connected to the arm at a second location distal to the pivot. The weight receiver is configured to hold one or more weights to modify a downward force provided at the handle.

The portable hand cycle is a user-stabilized device for upper body exercise. The portable hand cycle is held in place using the weight of a user, holding a platform against the seat of a chair, couch, or other surface. In a sitting position, a riser connected to the seat extends up and away from the user. The riser is optionally of an adjustable length in order to fit users of different sizes. The riser ends with a sleeve that encloses an axle, the center of which is placed at chest-level with respect to the user. The crank is connected to a pair of crank-arms that in turn terminate with grips. To operate, the user extends her arms and holds the grips in her hands. Her rotation of her hands moves the grips, which in turn rotates the crank-arms, finally rotating the axle.

An exercise machine includes a treadmill body and an upper limb weight training mechanism. The upper limb weight training mechanism includes a guide rail, a slider, and a weight unit. The guide rail is fixedly connected to the treadmill body. The slider is connected to the guide rail and moved back and forth on the guide rail. The slider is provided with a handle. The weight unit is disposed on the slider. The upper limb weight training mechanism can be straight pulled up and down to train the muscles of the upper limbs while the muscles of the lower limbs are trained.

The present invention provides a leg rehabilitation exercise apparatus, which includes: a base; a seat arranged on the base; a leg exercise frame arranged on the base; an upper rotation-supporting member arranged on the leg exercise frame; a lower rotation-supporting member arranged on the leg exercise frame; a reciprocating motion section including a left lifting/lowering motion section, a right lifting/lowering motion section, an upper connection section, and a lower connection section; a left lifting/lowering member arranged on the left lifting/lowering motion section; and a right lifting/lowering member arranged on the right lifting/lowering motion section. The left lifting/lowering motion section and the right lifting/lowering motion section are operable to do lifting/lowering motions in opposite directions. The leg rehabilitation exercise apparatus of the present invention achieves an effective result of training quadriceps muscles of thighs and shanks and is also an operation safe device.

An apparatus used for cardiovascular workouts and strength training workouts contains a treadmill, a first weight-engaging pulley mechanism, a second weight-engaging pulley mechanism, a first guide channel, and a second guide channel. The treadmill is used to complete the cardiovascular workouts. The first weight-engaging pulley mechanism and the second weight-engaging pulley mechanism are used for strength training. Since the weight arrangement of the apparatus is movable along the first guide channel and the second guide channel, the user can complete a wide variety of strength training workouts. The apparatus also contains an incline-adjustment mechanism, which orients the treadmill belt track to simulate an incline or a decline. A belt direction-reversing mechanism of the apparatus helps change the direction a belt that is layered along the treadmill belt track.

An exercise machine support system for providing increased versatility including inclination or declination of an exercise surface, a reduction in the overall length and width of the exercise machine, and an enhanced user interface which reduces the risk of injury. The exercise machine support system generally includes a cantilevered exercise machine which is adapted to have a variable angle of incline or decline with respect to a horizontal ground surface. The exercise machine will generally include a base and a support which extends between the base and the exercise machine. The upper end of the support is connected to the exercise machine by a first pivot such that the exercise machine pivots about the support. An adjustment device may be utilized to pivot the exercise machine and thus adjust its angle of incline. Various types of adjustment devices are disclosed, including an actuator, ratchet-and-pawl, gears, and cam.

An exercise machine creates a simulated continuous resisted climbing motion. The machine includes a floor- or ground-contacting base frame and two or more substantially vertically oriented uprights, wherein at least one upright is rigidly connected to the base frame. The machine further includes two handles and two foot pedals, each handle and each foot pedal being movably engaged with an upright for linear reciprocating motion along the upright. The handles and foot pedals are interconnected so that they move in unison. An adjustable resistance mechanism is operatively connected to the interconnection of the handles and foot pedals to provide adjustable resistance for the simulated continuous climbing motion.

An active suspension orthotic support system is disclosed. The suspension orthotic support system comprises at least one variable resistance beam extending from a heel section to a mid-arch section of the footwear, wherein rotation of the variable resistance beam from a first position to a second position causes a resistance provided by the variable resistance beam to vary between a minimum resistance to a maximum resistance.

A physiotherapeutic device is disclosed. In an embodiment a physiotherapeutic device includes an arm trainer configured to rotationally move arms of a patient, the arm trainer having a first axis and a leg trainer configured to rotationally move legs of the patient, the leg trainer having a second axis, wherein the first and second axes comprise an adjustability in height, wherein a distance of the first axis to the second axis is constant, wherein the arm and leg trainers are adjustable in height so that an adjustment in height results in different exercising positions.

A treadmill has a front or rear set of pulleys and a looped running belt. The pulleys rotate with the movement of the belt, e.g., when a user walks, jogs, or runs on the treadmill. The pulleys are mounted on a rotating roller tube so that the roller tube rotates with the pulleys. The roller tube is mounted on a stationary shaft using bearings on each side and a one-way device that allows the pulleys to rotate in one direction. The rotation direction corresponds to the movement of the top of the belt from the front to the rear of the treadmill. The one-way device prevents the pulleys from rotating in the opposite direction, preventing the top of the belt from moving from the rear of the treadmill to the front. The one-way device may be a sprag clutch. The treadmill may be a motor-less, curved treadmill.
