On my road back to overall physical fitness I have revived my interest in strengthening my grip. I have always found this to be a relatively fun aspect of training. I can do it at off times or in between workouts without too much overall strain on my system. My mainstay are the Ironmind grippers. I have the full set from trainer to #4, but have never gotten past #2. I keep these with me every day and use them during a break or sitting in the car when early for an appt. etc. My goal is to be able to close the #3 (someday). I also do thick grip dumbbell work, weighted finger curls, wristrolling, and a half dozen other grip exercises on various arcane devices. Another favorite is the Rolling Thunder. It is a 2" or 2.5" thick one handed deadlift handle that is smooth and revolves so that you really have to grip it, a claw or hook won't work, to lift. It has a vertical tube to stack weights on that hooks to the handle with a carabiner. Very challenging. Anyone else work their grip specifically and what type of exercises do you do?
