Leg Extension

The leg extension is a resistance weight training exercise that targets the quadriceps muscle in the legs. The exercise is done using a machine called the Leg Extension Machine. There are various manufacturers of these machines and each one is slightly different. Most gym and weight rooms will have the machine in their facility. The leg extension is an isolated exercise targeting one specific muscle group, the quadriceps. It should not be considered as a total leg workout, such as the squat or deadlift.

Famous quotes containing the words leg and/or extension:

    “Entrance and exit wounds are silvered clean,
    The track aches only when the rain reminds.
    The one-legged man forgets his leg of wood.
    The one-armed man his jointed wooden arm.
    The blinded man sees with his ears and hands
    As much or more than once with both his eyes.”
    —Robert Graves (1895–1985)

    “We know then the existence and nature of the finite, because we also are finite and have extension. We know the existence of the infinite and are ignorant of its nature, because it has extension like us, but not limits like us. But we know neither the existence nor the nature of God, because he has neither extension nor limits.”
    —Blaise Pascal (1623–1662)
