An adjustable hip and thigh exercise apparatus which is releasably attached to the end of a wall including a frame, a clamp, a lever pivotably attached to the frame, a lock to allow the lever to have a number of initial positions, a lengthening assembly to allow the lever arm to be lengthened or shortened, and a variable resistance element. The apparatus is attached to the wall and aligned with the pivot point of the user's hip. The user sets the desired resistance of the exercise machine and bends his or her leg over the lever and causes the lever to rotate from the initial position to a second position thereby exercising the muscles of the leg. The user can also adjust the range of motion desired to exercise the leg muscles as well as the resistance against which the leg muscles will exercise.
