Had an interesting discussion with a friend yesterday wanted to get some other opinions. What is the correct starting position for a chin up? I have always done it from the complete bottom. My arms are straight, my shoulders are not taught, they hang up next to my ears. He tells me that although it is admirable to do them from the bottom, the fact is that if you are allowing yourself to go limp, you are making too difficult to do the chin up, particularly on multiple sets. He advocates going down as far as you can without relaxing your muscles, so your arms would remain slightly bent, if at a 10degree angle, even at the bottom.
