In reply to MikePemberton: Just what these lads have said here. Tendon strength takes much longer (3-4x) than muscular strength to gain. It also has to be trained in a very different way to muscle, as if you over train a tendon in a session you can be out of action for months, whereas over training a muscle will often take a week or so. If you isolate the fingers in your training using a campus board and use it 3-4 times a week, you will get strong fingers!
P.s. Body-builders have small penises before they get big. That's why they get so muscle-y, it's overcompensating.
Also steroids shrink your cock and balls and give you tits, due to your body upping the oestrogen to level out with the testosterone.
