as HIT perceives volume training as a bad move what you are saying appears to be that you need to train badly before training properly in order to benefit from training properly!
Anyway, anyone new to training needs to learn the exercises first and going to failure is a short path to injury so experience does count.
Also, i'm not sure about the need to go to failure - it hasnt borne out anecdotally for people, nor conclusively in studies, though it remains a favoured argument in forums!
Abreviated training, 2-3 times a week for 30-45 mins focussed on compound exercises, that does work.
A lucky few can recover still faster, an unlucky few need more time still.
