This is a video explanation of a technique/exercise I came up with to specifically strengthen the ring/pinkie finger of your hands for helping in closing big grippers These 2 fingers limit your end range closing strength due to a bio-mechanical disadvantage. There's a mechanical advantage in the fact that the RP fingers have the most leverage on the gripper handle BUT the problem is that they are considerably weaker than the index/middle fingers. If you're stuck on the last little bit of end range on your goal gripper then this will remedy that problem. Be sure and experiment with the variables to see what works optimally for YOU with this technique. Thanks for watching!
