    Default Squat class lever

    Is the class lever in the squat is the same as in the deadlift?(class 1 lever)
    It is not mentioned in the chapter of squat, just the wrench and the bolt example of moment arms.
    In the chapter of the deadlift itís wrore that the deadlift is better explained as ďclass 1 leverĒ rather then in the wrench and bolt exemple.
    And then itís wrote that the hip is class 1 lever-does it mean he worked as a class 1 lever also in the squat?

    In the chapter of the squat the example is of the wrench and the bolt.
    When I have longer moment I have more power.
    Now, in barbell training the hand turning the wrench is the weight of the bar.
    Why is the recommend thing to do is to shorten this distance if in the wrench the advice is to lengthening the wrench.
    Or I didnít understand something or your analogy isnít correct.

    This is discussed in the book. What is your first language?

    Think about which side of the fulcrum the force being applied to and youíll find your answer.

    So according to what to say
    Squat is a class 1 lever, that is not the same as wrench and bolt analogy?

    It is the kind of question which answer is obvious to anyone for whom the said answer could be of any use.

    But in order to end the suspense, yes, it is still a class one lever.

    I’m still trying to figure this out, I have something in mind, tell me please if I’m right or wrong.

    Gravity pulls the bar down(the hand in the analogy).
    when there is more weight, the fulcrum(hip joint) will open up with less effort.

    Now to close this fulcrum(hip joint)
    The force will come via kinetic chain from the primary muscles operating through the back to bar.
    If the bar(the hand) will be far from the fulcrum the force will decrease.
    This is why it’s better to reduce the moment arm?

    In the chapter of the deadlift he says that the deadlift is a class lever 1,
    The short segment lift the long segment, I can understand this.

    But what heppens in the squat?

    The squat is not "a lever." The deadlift is not "a lever." They are movement patterns that rely on several different levers. You have not read the book. Please stop typing and read the book.
