Watch any part of blood and guts and you will see Dorian get into the zone pre working set, his mind set and aggression is ready for that working set. Its took to true failure were many of us fail and think that's failure he goes past it. Infact look at any hard core pro training and look at the difference in how they train to guys in our gyms. Many think failure is when they cant do anymore, well sorry fellas it isn't. If that BB was was crushing your mum or children you would find the power to shift it, its all in the mind., Many times I miss true failure because my mind wasn't right, I have to tap into my zone, my inner self and release the adrenalin what will make me do more reps and take my body to failure. How often on a set you think that's it, that's failure and stop and straight afterwards you think fuking hell I could of done more why didn't I push harder so you get hold of the weight again and go again?? well you should never ever feel that you should be at total failure and unable to perform another rep. That's the difference that's what true HIT is. Not everyone can do it and it takes time to adjust the mind and body.
