I think a lot of people get in trouble with pain from pull-ups. I love the exercise, but I no longer just walk up to the bar when I am in the mood. I first do a set or two on some resistance bands I attached to a ceiling, to warm up. They give about 35 pounds of resistance.
I weigh over 200 pounds. I would never walk up to a weight bar and military press 200 pounds cold. I regret that I used to walk up to a pull up bar and pull down with 200 pounds of force cold, I think it caused me shoulder trouble that was made worse by long days of intense keyboard/mouse work, and the caffeine in one or two cups of coffee per day.
