Full Range of Motion (ROM) Fanatism

Everywhere you go you see fanatism about ROM. The hell ? if the bar doesn't touch the chest, it doesn't count. if you don't squat lower that paralel to the ground, it doesn't count. etc.
Where does all that comes from? Competitions? most joes don't compete, and never intend to. Arnold in the encyclopedia says that you should always use full ROM when you train, could it be his fault? (joke)
I don't know what wrong with a shorter range of motion, in fact, i have used some short range of motion with great success in my bodybuilding and powerlifting "carrier".
I am a skinny type with long arms, long legs and a short chest. i suck badly at bench press and squat. Deadlifting for me is the most rewarding.
How do i improve my bench if my arms are long? easy, by shortening the distance the bar have to travel, or by making the leverages easier. how do we do that? by either taking a wider grip, or by binging the chest more upward, and arching the back. but there is one more way : you can also reduce the range of motion. OMFGTH this is illegal !! you gonna get caught by the police if you do this, and they will rape you in the asshole ! more seriously, by reducing the ROM, you will fin yourself lifting a lot more, and it will helps you overcome your walls.
say your benching 200, for one rep. you cannot seems to do two reps out of it. just reduce the ROM, and do three reps. next time you do five with the same weith, and the next time, you increase the weight. you muscle will adapt to the new wieght very quickly, and they will grow thicker, and more powerful. and when you will try again your one rep max, my guess is that you will have a new PR.

This technique is very well known (or was) to increase muscle mass and strength very fast. it will increase your power dramastically. but to everything there is an end: even this way you have to stop increasing the weight at some point, deload or rest to make sure your muscle have the time to rebuilt. Works best big compounds like the bench press and the squat.
