Bottom line is that the longer the chain that is producing the "wave" motion, the more spread out in time the effect of gravity will be on the overall mass, providing a kind of "anti-gravity" resistance - where the upward moving parts are pushing against the downward moving parts. It' can be thought of as "slowing down the effect of gravity" on the overall mass, resulting in increased resistance in the downward direction. when you are pulling down.
Basically, here are the physics of it: Using the time delay of chain links will allow resistance to be more equally spread out in all directions, as opposed to dead weights which have a single mass. A single mass will always have a single momentum vector which will have a constant force against gravity. Chains spread that out by having multiple masses with a time delay on their vectors, which change constantly as they are being acted on by opposing momentum vectors in the chain.

can't you just use a lite weight ?
