Alas brother , even the great brophet Arnold , having no soft spot on his body chiseled by the AllLifter himself , had one in his heart , for TW cardio . Nay , he never beeshed us to run , in the fashion of the hamster , upon the milling treads , but he gave us the wisdom to minimize rest between prayers of 5 x 5 . Increases in the rate at which the swoledier ' s heart doth pump blood shall not be those of a resting pace . Nor should it become so during the time for recovery , lest lactic acid builds to an unmanageable level . We are all well advised to limit rest to no more than one score and ten seconds between sets , else our swoliest of muscles , the heart of the swoledier , dost lose its mighty pump . Wheymen .
