## Abstract

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.

wherein each of said link units further includes a handle pivotally connected to said support frame unit and movable along with said first pivot arm; and
wherein said support frame unit includes a base frame, an upstanding frame connected to said base frame, and a rotatable rod connected transversely and rotatably to said upstanding frame, said first pivot arm of each of said link units being fixed to said rotatable rod, each of said link units further including a first link rod fixed to said rotatable rod and moving synchronously with said first pivot arm, a second link rod fixed to and moving synchronously with said handle, and a transmission rod pivotally connected between said first and second link rods.

### Claim 2 (depends on 1)

The exercise apparatus as claimed in claim 1, wherein said first pivot arm has a pivot end portion pivotally connected to said support frame unit, and a movable end portion opposite to said pivot end portion and pivotally connected to said pedal rod, said drive rod including a first rod section having one end pivotally connected to said crank wheel unit, and a second rod section pivotally connected to an opposite end of said first rod section and slidably sleeved on said first pivot arm, said second rod section being slidable on said first pivot arm between a first position, in which said second rod section is close to said pivot end portion and said movable end portion has a maximum pivoting amplitude, and a second position, in which said second rod section is close to said movable end portion and said movable end portion has a minimum pivoting amplitude.

### Claim 3 (depends on 2)

The exercise apparatus as claimed in claim 2, wherein said first pivot arm further has a plurality of positioning holes formed spaced apart along a length thereof, each of said link units further including a positioning member disposed on said second rod section for selectively engaging one of said positioning holes.

### Claim 4 (depends on 1)

The exercise apparatus as claimed in claim 1, wherein said pedal rod is substantially L-shaped.

### Claim 5

An exercise apparatus that simulates a hill climbing exercise, comprising:
a support frame unit;
