Yes i pyramid say i am doing chest dumbell press i will start at 50 lbs for 12 reps then go 70 for 12 reps then 90 for about 10 Then after that i will start 4 heavy sets from 130 up to whatever feels heavy that day.hope that helps alittle bit
Yes, it helped a little bit , you damn midget

(really, really jocking, here!!! I love you, man!!!

)
But there's still one piece of the puzzle missing that still 'puzzles' me (LOL) : definition of FAILURE, by your accounts. Let's say, your working sets on the dumbell presses start with the 130 pounders and then you move your way up to whatever feels heavy on that particular day. Do you hit ABSOLUTELY FAILURE with those 130's? At what rep range? And then, on your 3 remaining sets, do you still go after that COMPLETE failure, where you can't move the weight in the positive portion all by yourself, at the same time you keep climbing up the poundages?
Because if you reach failure , absolute failure in all those working sets, while still progressing the poundage (like the chart outlined above), I'm sure that 10 reps to absolute failure with the 130s would be equivalent to a severe decrease in reps on your sucessive sets, as you keep on incrementing the weight, right?!
Still, that's one HELL of a high intensity training. Not for everyone, for sure. It takes a different kinda animal, most def.
