iPhone case doubles as 22-pound dumbbell

May 21 (UPI) -- A Japanese company is making it easier for the phone-addicted to build muscle with a 22-pound iPhone case.

Telecom giant Softbank announced the 22-pound dumbbell case, billed as the world's heaviest for the iPhone, is now for sale on its website for about $100.

The case is composed of a standard dumbbell with a permanently-affixed phone case, designed to face the user at a 25-degree angle, which Softcom said is "ideal for watching movies" while pumping iron.

The company website shows the "macho case" also is usable as a tabletop iPhone stand, a doorstop and a tool for do-it-yourself crafts.
