In reply to JimboWizbo:
I followed Chris Webb Parsons hangboard program for 6 weeks and drastically improved my crimp strength, I went from barely being able to hang a campus rung one handed for 1 second to hanging for 8-10 seconds.
(he talks a LOT but stick with it)
I would have started another cycle but I managed to break myself (in an unrelated incident) so I never really got to see how it helped on many problems, i know it's not closed crimps but with that kind of improvement you'd barely even need to closed crimp!
