(AP) -- A Japanese company is offering an iPhone case that will work you out while you carry it.

Telecom giant, SoftBank, just announced the 22-pound dumbbell case for the iPhone X.

The phone accessory actually has a dumbbell permanently attached to it.

It is designed to be inclined at about 25 degrees... optimal for watching movies.

The case is being billed as the world's heaviest case for the iPhone.

It's for sale now on SoftBank's website for about $100.
