With all this talk of training half crimps when training on a fingerboard, I thought I'd add a couple of sets of repeaters with a half crimp on to the end of my fingerboard session. (the big four finger edge of a Beastmaker 2000)
To my dismay, I got half way through the first set and my right hand "fell" out of a half crimp position and into an open handed position. This has happened a couple of times now, I get half way through the set and my half crimped hand seems to relax into an open handed position.
Obviously my half crimp is weaker than my open hand but is part of the reason for this poor performance likely to be fatigue, having already done 9 sets of repeaters with variations of an open handed grip? And is a half crimp more intense or something, should I be doing it at the beginning of the fingerboard session?
