Whenever I start to either lose a little strength or lose "the feel", I always drop back to 5 sets of 5,----15 sets major----10 sets minor----however I train my bodyparts twice in a 10 day stint---
but the key is to take the same weight for each set of 5 but take a weight that you could do 8 reps----stop at 5 reps but thing you want to concentrate on is holding the squeeze at the top for a 2 or 3 count if possible ---the squeeze should be at 110% intensity(try to squeeze the muscle out of the skin and hold)
your first 3 sets will probably only yield about 80% max but your last two sets of the exercise should be somewhere around 100%-----and when you add in an squeeze or hold thats two to three times the norm your intensity goes through the roof without having to worry about poundages....

if that doesn't interest you, i can tell you what I see some really big fuckers doing out here
drop sets ---drop sets ---drop sets---and more drop sets
training very fast 30-45 sec rests-------rest pause---and gaint setting almost everything.
I also see heavy stretching of the muscles as part as their workouts(something I;ve never seen on the east coast)
i've seen a guy at the end of his chest workout do 5 sets of flat flys but all he did was take 90lb dumbbells and hold them at the very bottem of a fly movement and try to hold them out for 30 seconds with no rest in between sets---take half that weight and see what I mean----pretty freaky
