Don't listen to the Nay Sayers! I know these Guys that started working in an automotive junk yard, and they were always picking up heavy things out of the mud, and dirt. They used their finger tips to pry loose Chevy 350 heads, and engine blocks. Before long their rings no longer fit, and their fingers got real fat with pure muscle. Then I knew this woman who was a masseuse, and her hands became inordinately wide due to the constant pressure she exerted on them while pressing down on the muscles of her clients. Now, think about OJ Simpson. He built up the muscles in his hands so much that the gloves used as evidence against him no longer fit. I'll bet he did a lot of finger tip push ups while waiting trial.
