An exercise machine and a dual resistance structure combining wind resistance and magnetic resistance are disclosed. The dual resistance structure combining wind resistance and magnetic resistance includes a rotating shaft, a wind resistance unit, and a magnetic resistance unit. The wind resistance unit is disposed on the rotating shaft, and includes blades arranged annularly. Each blade has a notch recessed in an axial direction of the rotating shaft. The magnetic resistance unit includes a magnetic resistance member and a magnetic resistance wheel. The magnetic resistance wheel is disposed on the rotating shaft. The notch of each blade faces the magnetic resistance wheel to form a moving space between the magnetic resistance wheel and the notch. When the magnetic resistance member is moved relative to the magnetic resistance wheel along a radial direction of the magnetic resistance wheel, part of the magnetic resistance member is movable in the moving space.

An exercise machine may include a frame, a resistance mechanism supported by the frame, first and second pull cables supported by the frame and linked to the resistance mechanism, a power rack attached to the frame, first and second handles selectively attachable to the first and second pull cable, and first and second pulleys. The power rack includes upright posts configured to have barbell holders adjustably attached thereto such that the barbell holders are configured to be adjusted in various positions between highest positions and lowest positions on the upright posts. The pulleys are configured to selectively receive the pull cables to enable the pull cables to be selectively attached to a barbell to assist or hinder a user in lifting the barbell in a combined cableand free weight workout, the pull cables decoupled from the pulleys for cable workouts.

A climbing exercise machine includes a beam supported on two columns supported on a base. Two handles are movably supported on the columns, respectively. The handles are movable in opposite directions. Two treads are movably supported on the columns, respectively. The treads are movable in opposite directions. An input axle is supported on the columns. The input axle is rotated as the handles and the treads are moved. A transmission case connects the input axle to an output axle. A disc is connected to the output axle. A frame is connected to the beam. A resistance element is supported on the frame. The resistance element includes a magnet. The resistance element is movable relative to the disc to adjust magnetism exerted on the disc by the magnets.

A weight training sled having (i) a chassis, (ii) longitudinally spaced rotatable wheels in contact with ground, (iii) a pair of laterally spaced push handles proximate a first longitudinal end of the chassis and (iv) a brake for applying resistance to one of the wheels, characterized by an elevated tow hook.

An exercise device having a first handle, a second handle, and a cylindrical chamber. The cylindrical chamber is oriented in that the first handle is attached at one end of the cylindrical chamber and the second handle is attached at the other end of the cylindrical chamber. The cylindrical chamber contains a system that facilitates magnetic, tension resistance. Bisecting the surface of the cylindrical chamber, is a knob connected to a fixed component that adjusts the magnetic, tension resistance within the cylindrical chamber.

An indoor exercise bicycle having a magnetic brake. The magnetic brake system has a pair of parallel arms each having a set of magnets. The pair of parallel arms moves along a track in a radial direction relative to the axis of the flywheel. The pair of parallel arms move toward and away from the flywheel not via a pivoting action. Instead, the pair of parallel arms moves linearly towards and away from the flywheel.

An elliptical exercise machine may include a base, one or more upright stanchions coupled to the base and extending upward from the base and supporting first and second cranks. The first crank may support a first crank arm. The first crank arm may support a first pedal leg hanging downward from the first crank arm. The first pedal leg may support a right pedal. The right pedal may be configured to swing forward and rearward and to raise upward and lower downward. The second crank may support a second crank arm. The second crank arm may support a second pedal leg hanging downward from the second crank arm. The second pedal leg may support a left pedal. The left pedal may be configured to swing forward and rearward and to raise upward and lower downward.

The present invention relates to selectively adjustable speed and incline levels for treadmills. An example treadmill includes a platform around which a belt rotates, a drive motor for controlling a speed of rotation of the belt, a linear motor for controlling an incline of the platform, a human machine interface configured to receive from a user a first selection regarding at least one of the speed of rotation of the belt and the incline of the platform, at least one manual lever configured to receive from the user a second selection to respectively refine the first selection, and at least one controller that selectively changes the speed of rotation of the belt or the incline of the platform based on the first selection received by the human machine interface, and selectively and respectively refines the first selection based on the second selection received by the at least one manual lever.

Exemplary arrangements provide leg training devices suitable for high intensity training of hip flexors while simultaneously training the extensors of hip and knee joints. The exemplary leg training devices include foot fixings which are permanent vertically movable components of the device, each of which are configured to releasably engage a foot of a user in operative engagement therewith while limiting the movement of the foot relative to the foot fixings. Each of the foot fixings is operatively connected to a suitable mechanism that provides a resistance force to vertical movement of the foot fixing by the user's leg. In exemplary arrangements the resistance force may be selectively variable with regard to the magnitude and/or point of application so as to provide the desired training regimen.

A resistance device capable linearly adjusting training load comprising: a rack unit with two vertical rods, and two sliding units, which are connected to a handle and a pedal; a linkage unit with a chain and a belt, and are locked on the connecting plate; and two damping units make multiple magnet pieces arranged on both sides of a fixing base, and a diamagnetic metal piece is arranged on the connecting plate, and set trough the fixing base to cut the magnetic circuit generated by the magnet pieces to form damping: When the user steps on the pedal, the connecting plate will drive the metal sheet to cut the magnetic circuit, and the damping can be changed to further achieve the effect of linearly adjusting the training load.
