Sri Chinmoy lifts 800 pounds overhead on a partial military press machine. Note that Sri Chinmoy is following strongman standards in lifting the weight only enough so that a piece of paper may theoretically be pulled from underneath it.
As the weight progressed, the amount of distance Sri Chinmoy could displace it, obviously would decrease. In this clip, pay close attention to the separation of the platform from the machine. You may need to watch the clip several times. The platform moves up at the peak of Sri Chinmoy’s expression (scream) of exertion.
