[The Stronger Sex]

That's an area that's resisting all my efforts. I know it doesn't have much muscle to begin with, but I see a lot of people with very developed wrists, even people who don't lift, and I'm talking about actual muscle mass, not just wide bones. I'm aware that part of it is genetic, but it's like I only have tendons where others have muscles. All my efforts have been sterile so far. Any tips on how to work that area for volume?
