The second-class lever is another example of a simple machine comprising a beam placed upon a fulcrum. In the second-class lever, the orientation and distribution of forces are different than in the first-class lever: The load is placed between the fulcrum and effort, while the force of the effort is directed in an opposite direction to counter that of the load.

“The goal in your pull-up work is 'more.' You want, you need, more pull-ups. The more you can do, the stronger you become. Muscular endurance, absolute strength, relative strength—whatever you want to define and measure gets better. Every personal-best pull-up is an event worthy of celebration. You’re going to live to be 100, but you’ll not get that many pull-ups, so treat the new ones like birthdays.” —Greg Glassman
