You don't know how to untwist cables?
Best forearm workout ever.
@coolboymew
Lift it up, so whatever's free can freely rotate, then pinch one end, then slowly run your pinched fingers down the cable, essentially massaging it. The free end will spin around. Once you've hit the end, repeat in the other direction.
@coolboymew
It can take many, many iterations. Especially on 100 meter cat5 cables.
And you'll look like Popeye afterwards. But chicks love veiny forearms.
@coolboymew
And you have to maintain tension the whole time. You can't checkpoint it.
Good luck, have fun, enjoy sexier forearms.
