I pretty much second what Soldier said. Supersets are great for speeding things up. Although I don't use them as often as I did, since utilizing Drop Sets more. I love those, they really burn the muscle fibers up. I especially like doing a normal workout for one group, then ending with a dropset to failure to end it. As for pre-exhaust, I'm up in the air on that one. I do more warm up sets, and more slowly than most people. But not only with a isolated movement, I start my typical bench press session with 2-3 sets from 135 to 185, hitting as high as 20 reps sometimes. Then I move up to using multiple plates and spots if needed.
