Anything on an angle like that is less than half the weight. It takes more strenth to do weighted hiking

I dont think they'll be adding that event to Strongman anytime soon.  :)

To be exact, a 45 degree leg press provides a mechanical advantage such that the weight lifted is actually only 70% of the load.


So a 45 degree 2000 pound leg press is actually 1400, which still is a big number :)


"The gentler than angle, i.e., the more it deviates from the vertical, the easier it is to lift. Most leg press machines today are on 45-degree angles, although some are far gentler. The cosine of 45 degrees is about 0.71, giving a 1:1.4 mechanical advantage. "
