Back in middle school, I remember learning about simple machines like ramps, pulleys, and levers for the first time. Like every other kid in the class, I was probably thinking, ‘Why should I care? I’m never gonna use this crap!’
Fast forward a decade to my graduate studies in biomechanics and movement science. It turns out this stuff is my jam!
As a matter of fact, the human musculoskeletal system is nothing more than an intricate network of levers (bones), with muscles acting on them to produce movement.
As such, this system can be analyzed in light of simple machine principles like leverage, or mechanical advantage, and the primary topic of this post: moment arms.
The upshot? Direct and purposeful applications to resistance training, of course!
