I'll use this to discuss my findings.
In my experience you need not and should not do your set rep scheme anywhere near your maximum capacity MOST of the time.
What I mean by that is that let's say you can do 5 x 3 with 300 pounds in the bench press with an all out effort, you might very well be able to get stronger just as fast by doing 5 x 3 at 240-270! or about 80-90% of your capacity (although your ability to train more frequently would go up.
It was a hard adjustment for me to make, and its kind of difficult to accept. If I could max 360, and do 5 x 3 at 300, I am suggesting that you could match the strength gains from the 5 x 3 at 300 by doing 5 x 3 at 240 to 270 which is only 67% to 75% of your 1 rep max. Training heavier causes more damage, and more stress and does not necessarily build strength faster.
And I am not talking about speed reps.
Another thing, I have found that doing 3-5 reps works BETTER than doing 1-2 reps with more weight. For the bench, my ideal rep range is 3-7 reps. Fewer than 3 and more than 7 does not work well. In the squat it is 2-5.
I tend to agree though, 10-30 reps is the basic range that has worked for me overall.
I like to start with all work sets at the same weight, but to gradually space them out.
So back to the 360 bench, who "could" do 300 x 5 x 3.
Let's start at 255 for 5 x 3.
Then go to 240 x 3, 250 x 3, 260 x 3 x 3
Then 235 x 3, 245 x 3, 255 x 3, 265 x 2 x 3
Then maybe 225 x 3, 240 x 3, 255 x 3, 270 x 2 x 3
Typically try to use even jumps and get at least 2 sets at top weight.
Lastly, I said stay at 80-90% maximum capacity MOST of the time. At least half.
Either do an all out workout, 300 x 5 x 3 in the example, and then do your next workout at 80-90% of that (240-270 x 5 x 3) OR spend about 2 weeks on full bore, and 2 weeks on 80-90% capacity. I have increased my max though by training around 80-90% of capacity in a given set rep scheme exclusively for 2-3 months straight.
