An exercise device of the type including a frame with a first crank assembly rotatably coupled to the frame about a first axis and a second crank assembly rotatably coupled to the frame about a second axis. A control system may be used in communication with the first crank assembly and the second crank assembly, which may provide a synchronous movement of the first crank assembly relative to the second crank assembly. A pedal arm may be provided with a first end pivotally coupled to the first crank assembly and a pedal positioned on a second end. A crank link may be used with one end coupled to the second crank assembly and a second end coupled to the pedal arm. The crank link may be movable on the pedal arm which may provide varying paths of motion of the pedals.

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 high knees exercise apparatus includes a base, a driving mechanism, a linkage mechanism and two magnetic resistance. The driving mechanism is located on the base and includes two driving member which is driven swung along arc path. The linkage mechanism is for leading the driving members swung reversely in response to each other. The two magnetic resistance devices are for providing magnetic resistances in accordance with swings of the two driving members respectively.

A leg exercise machine includes a frame and a swinging mechanism. The swinging mechanism includes two parallel tubes, four swinging rods and two pedals. The tubes are supported on the frame. Each of the pedals is connected to two corresponding ones of the swinging rods. Each of the universal joints connects a corresponding end of a corresponding one of the tubes to an upper end of a corresponding one of the swinging rods.

Exercise machines having a user support and at least one user engagement actuator assembly wherein motion of the at least one user engagement actuator assemblies is resisted in both the push and pull directions by the resisted rotation of a one-direction flywheel that is operatively engaged with a braking mechanism. The resistance of the push direction can be less, greater, or equal to the resistance of the pull direction. Each user engagement actuator assembly can be configured to create various unique push and pull exercise stations. Multiple exercise stations can be mounted on each machine that can be operated independently or concurrently.

An exercise apparatus includes a support frame unit, a crank wheel unit disposed on the support frame unit, a resistance unit for providing resistance to the crank wheel unit, and two link units respectively disposed on left and right sides of the support frame unit. Each link unit includes a first pivot arm pivotally connected to the support frame unit, a pedal rod pivotally connected to the first pivot arm, a second pivot arm pivotally connected between the support frame unit and the pedal rod, a drive rod pivotally connected between the first pivot arm and the crank wheel unit, and a foot plate disposed on the pedal rod.
