you know more about this stuff than this newbie, but for me, if i'm going 5-8 i take atleast 2 min between. There has to be time for the glycogen to be replenished-or whatever all the scientific explanation is- i just know (for me) if i dont adjust my rest to the intensity level i dont get a good wo.I've found the same to be true about rest between wo's. If i go to absolute failure on my deds i need an extra day to recoup, or my next wo stinks. Take a longer time and see what happens, play with the variables untill it changes.
ps did u get that name from the "outsiders" by se hinton?
