In today's edition of Things That Exist That We Definitely Didn't Need™, we have for you a rather unusual iPhone case. One that doubles up as a dumbbell that you literally have no other choice but to work out with.

Japanese telecom giant Softbank is selling this contraption for around $100 (£75).

The case—reported to be the heaviest in the world—could come in quite handy for people keen to cut down on their iPhone addiction.

The dumbbell weighs 10kg, which is quite a lot for just one arm. Especially when you're phone is permanently attached to it.

But, it could very well get rather tiresome if you have to pump iron any time you need to make a call, text your mates, or even just check your Instagram notifications.

I think we'll pass on this, thanks!
