Before I found out I had carpal tunnel in my wrists, I could do 3 sets of 10 of overhand grip...last set was a bit shakey so probably more like 8 on the last one.
Now- cannot even do them . They are a wicked excercise no doubt- probably one of the best.
"I believe that banking institutions are more dangerous to our liberties than standing armies. If the American people ever allow private banks to control the issue of their currency, first by inflation, then by deflation, the banks and corporations that will grow up around the banks will deprive the people of all property until their children wake-up homeless on the continent their fathers conquered."
-Thomas Jefferson 1802
