6 SoftBank Dumbbell Case
Your iPhone probably already goes to your gym with you. With this case attached, on the other hand, your iPhone might actually be an alternative to going to the gym. This case, created and sold by Japan’s SoftBank, is pretty much what it sounds like.
Essentially, it’s a 10-kilogram (22-pound) dumbbell that’s permanently attached to an iPhone case. Presumably, the goal is to encourage working out your muscles while you’re using your phone. If that sounds appealing, you can pick one up here for around $100.
