What science they based this on is unknown to me . It seemed to work for pressing
overhead after I modified the portable power rack I bought from them . They sold
this piece with way too narrow a spread between the uprights . Familiar tune .
Market and sell first don't sweat customer problems too much .The course that
came with it had Bill March doing the exercises . He could not have preformed
the demos in the portable version of the rack they sold .After puttering around for
several months with the iso holds I came to the conclusion this was a bandwagon
training type deal (York's flavor of the month). Good squat and bench press rack
(outside the pins ) and a sneaky good leg press situation , if set up right .
We must see these 6 secs holds but we must determine range and resting periods.
