We decided to make the HSPU scale to a simple Barbell Press to keep the standard consistent across the board. The same goal applies for doing all the movements unbroken. That is going to be the best way to attack the workout if you want to make it past the 10/15min mark.
NOTE: Hold the same weight across the bench sets. Between each set of bench perform 15 ring rows, preferably with feet elevated on a 20″ box.
