ok.. i classsify grip as 2 kinds. one grip is that u use your
forearm muscles only
another grip is u use your forearm and back(lats) muscle. try
recriting muscles from your lats and grip. you will feel that the
grip is even tighter and harder.
is like when u are angry and wanna puch a person... upper body
stifffens up and your grip will tend to recruit from back
muscle
