I just had a flashback to when I was a little Boyscout and I was shaking hands with my Scoutmaster.
>we go to shake hands
>he's a big guy and I'm very little at the time so I want to be sure my handshake is firm enough
>we begin the handshake and I start off with what I thought was a decent squeeze
>he has such huge forearms so his grip on my hand is naturally pretty strong
>I decide to try to even out with him so I don't seem like a bitch
>I start squeezing tight and he gets a dangerous glint in his eyes
>the next thing I know he says "YA NEVER GRIP A WOODCARVERRR" and my hand is subsequently crushed to a pulp
Long story short, you should buy a woodcarving knife and start making little Santas and trains or some shit because it's fun, manly, makes for good gifts, and it will give you ridiculous forearm strength.
