In general, cracking your knuckles is not a bad thing, but having the urge to crack your knuckles a lot usually indicates a muscle imbalance or something is out of alignment. These finger stretches & exercises may help fix those issues.

Starting off with ball or towel squeezes and using a rubber band will help strengthen your flexor and extensor muscles of the fingers.

Active movement and stretches as your finger joints and opening and closing your hand as wide as you can will help keep the joints flexible and mobile to prevent cracking and popping.

Finally, wrist and finger stretches, like for your wrist flexors, help open up the whole arm to loosen them up. A reverse hand clasp and prayer stretch do a great job of loosening the forearms up as well.
