WARNING: Training with hand grippers is extremely addictive! They will be hard to put down, resulting in overtraining and possibly extreme hand soreness.

Don't neglect extensor training.

Extensors are the muscles on the back of the forearm involved in opening the hand and are extremely important to hand health and strength. Wrap a thick rubber band around the ends of your fingers and open your hand for as many reps as possible. For a real challenge, place both rubber bands on one hand - TRY TO OPEN YOUR HAND! Buy a gripper from me and I'll include two thick, heavy duty rubber bands.
