Check out Jedd’s blog if you have not done so yet. Jedd Johnson is one of the countries top grip athletes, and one hell of a trainer. I have emailed Jedd back and forth for the last year and he has been extremely helpful and supportive to my training and deployments.
Jedd has wrote the best Bending resource on the Internet, the Diesel Crew bending e-book. It is a complete resource, with history, methods, rating of stocks, progression plans, and about 50 bending assistance drills. It features links to bending videos, and online stores for stock. I can not recommend this enough!
