Came close to a one arm chin today--and then felt a nice pinch in my neck. This has happened before, so I stopped right away and even though it's painful, I have full ROM in my neck. Does this suck? Totally. But trying to "gut it out" isn't going to do any good, so I stopped and live to fight another day. Here's what the training looked like:
Seated MP 40kg x 2 x 3
Muscle ups on rings: 5x5
One arm chin negatives 1/1x3
Chin+Butterfly Cross (will post a vid) 1/1x 3
One arm chin attemps 1/1, 1/0
On the plus side, I got about 3" away from lockout.
