Most lifters, and other athletes, will be more concerned with their form and range of motion. They want an equal balance of strength and joint/muscle (among many other things) ROM needed for a select sport. Also as a preventive against spot related injury.
Hardcore BB'ers just want the most size any way they can get it. BB'ers have always been the pioneers of new and unique training methods. Way ahead of the curve. This would also include diet and of course drug experiments (sorry to say). They step out of their own reality box and away from what is thought the proper way to train. That is, strict form and full ROM. I am sure there are some advance BB'ers who do train by the book with perfect form. But for the last 15 years, or so, just about every Pro or top BB'er I have seen or heard about in SoCal, depends on mostly middle range reps, done a a very fast pace. The tension is kept upon the muscle area throughout the exercise. The BB curl for example, once started, is never raised to a full contracted top position or lowered (extended) fully to the bottom of the lift. Always with-in the 2/3's range. Reps are around the 6 to 10 range, usually.
A limited style of heavy training reps/sets is not meant for everyone. Some guy's will prefer stricter ROM form and moderate weights and make good progress that way. Others, a slightly looser style with a little cheat on the last few reps. Or pure light pumping movements with extra reps of burns thrown in..The injury rate, surprisingly, does not seem that much of a worry, if proper warm-ups are not taken, with those 2/3's or limited ROM's for some people. I do believe that a 6 to 8 week protocol of serious heavy mid-rep range workouts can give a boost in muscle size and strength to a lot of guy's, from time to time. Good Luck.
