Do I have to order from ironman or are COC grippers sold in fitness stores in Boston? How about the forearm blaster? Havent seen one sold around here
Get yourself any kind of gripper, what quality isn't as important IMO. If you get hooked onto Grip Training, you will get CoC from 1-3 anyways.
Consider the first one a start. Make sure it has enough resistance. My advice would be for you to get a gripper that you almost can close, then proceed to do static holds with it two-three times a week, using the other hand to help close it.
After a few weeks you'll be able to close it yourself.
