Yesterday I ordered my 2nd Captain of Crush Hand Gripper. Years ago I bought the #1, which requires 140 pounds of pressure to close. It took me a long time before I was able to close it end-to-end in both hands. Now, I am ready for the next grip strength challenge. The #1.5 requires 167.5 pounds of grip strength to close.
I wonder how long it will take me to close the #1.5 end-to-end in both hands?
UPDATE (May 19, 2010): I was able to close the #1.5 end-to-end in both hands on my first attempt. Now I am wondering if I should buy the #2 (195 pounds) or #2.5 (237 pounds).
