So my thumb pad is developing nicely with dynamic and iso pinches and that's helping my gripper stay in place on the thumb side. However, the pinky side of the handle just keeps wanting to slide down and I'm curious if there's something I can do to building up the pad on the pinky side. It seems really hard to target this area in a way that gets anywhere close to an actual pump like with the thumb pad before the pinky/ring finger is worn out. Any ideas for getting some hypertrophy in this area?
Also, any technique tips I may be overlooking to prevent the pinky side of the handle from sliding back? I'm driving my thumb forward to create a pocket for the handle but the pinky side seems too far away for my thumb to brace it. My hand measures 7 3/4, so I am a bit on the small side but I do think some more muscle mass on the pinky side would help a lot.
