on bench, squats and deadlifts i warm up really well and hit 4 sets - 5,3,3,2 reps all explosive and with a pause like i was in a lifting meet.
all other lifts are in the 6-12 rep range in a pyramid fashion with perfect form and a slow negative.
12-14 sets for chest, legs and back
6-8 sets for shoulders, bi's, tri's, calves, abs and forearms...
low volume has always given me better "strength" gains...
i train in an attempt to get more weight OR more reps every workout when i'm bulking...every set is extremely intense and taken to positive failure, no help at all from spotters unless it's a drop set and i want to crank out a few extras. usually lift in a pyramid weight layout but sometimes i'll do supersets and drop sets to change stuff up.
