Here's the problem....

...everything is connected. Wrist flexors and forearm flexors wrapped by extensors. The grip is easy to overwork. Once over worked and fatigued, it can take weeks to recover. Months if you continue to train like a monster. Farmer walks are great but they destroy the grip for a disproportionate amount of time. Typing on a keyboard can be tough and become a challenge. The only way I know to recover a grip quickly is to see a massage therapist to work the area and then rest the area. If you know of a better, less expensive way, please let me know. Oh, and a hot tub works pretty slick as well.
