-Grip lock seems to happen on eagle giants more frequently than anything else. I've heard people claim that it happens when the gymnast tries to re-grip
-I've heard it happens when grips are too long.
**I know it's not as simple as eagle giants and long grips cause grip lock because I've personally swung high bar for >25 years, and I like to wear my grips long and do lots of eagle work.
I currently use reisport protec grips, which don't seem to stretch at all. I wonder if they are 'safer' for avoiding grip lock?
