Lever Lever A lever ( or ) is a simple machine consisting of a beam or rigid rod pivoted at a fixed hinge, or fulcrum. A lever is a rigid body capable of rotating on a point on itself. On the basis of the location of fulcrum, load and effort, the lever is divided into three types. It is one of the six simple machines identified by Renaissance scientists. A lever amplifies an input force to provide a greater output force, which is said to provide leverage. The ratio of the output force to the input force is the mechanical advantage
Front lever lever, straddle front lever, and finally on to the full front lever. At any stage of learning the skill the gymnast may perform pull-ups in the front lever position of their choice. A front lever held with just one arm. The body is often turned sideways in this variation The body is kept horizontal while the gymnast performs a pullup. In this variation the performer leans forward from the lever position, bringing the legs down and arms up until he/she reaches the top of a regular pullup. From here they lean back again, straightening the arms and returning to the
