In reply to GDes:
> The reason you can't find much info on it is probably because they aren't that useful as a way of training for climbing. You will however, find tons and tons of info on fingerboarding. Coincidence?
Or just less fashionable? There are lots of variations on pull-ups - weighted, power, french, typewriters. Pull-up sessions have a part to play - even if you are already strong it would seem....

The double world champion in bouldering Dmitry Sharafutdinov: How to increase maximum power? (He can do 75 pull-ups static and 110 dynamic).
"First, the maximum number of pull-ups on the bar as well as on the fingerboard. Before winning the world champion in 2007 I prepared by doing 10' to 20,000 pull-ups per month. In the morning I was training between 6 to 10. In the evening from 15.00 to 22.00. This is a very difficult method of training. I do not recommend it. An exercise on the bar is 20 sets of 20 times, rest between sets 3 - 4 minutes. Then fingerboard, active grip 15 sets of 15 times.
Before winning in 2011, I did 3' - 5,000 per month as I increased the load using weight belts etc. Jens, you have to say that it is very difficult and dangerous. The 2007 method is hard for your heart and the technique for 2011 puts a lot of stress on the joints."
