You can try rubbing alchohol to toughen up the hands. Vinnegar also works. Don't sand the knurling off the gripper whatever you do [img]/images/graemlins/smile.gif[/img]

Like Blarg said go for negatives and timed holds, 10 seconds is good. If you get really into gripping get an Ivanko Super Gripper to go with your normal grippers. This allows micro progression.

Good luck with it gripping is a great hobby.
