Imagine that everytime you answered a phone call, responded to a text or checked your Facebook you could burn calories and build muscle mass. It sounds great but there's a catch: you have to carry around this three-pound iPhone case.
It's called the ToneFone. Here's the audacious description from DesirableBody:
The ToneFone is a revolutionary new case for iPhone 5 and 5s that turns your phone in to a weight loss device by increasing its weight to up to 1 or 1.5kg - allowing you to work out wherever you are. It’s simple: you get a text you get fitter, your mum calls you, you get fitter, you check Facebook and you get fitter, even when you order a takeaway you get fitter. You can take it with you anywhere and every time you pick your phone up you’ll be working out.
It seems like the novelty of schlepping this big iPhone case around would wear off really quick. But the first batch of ToneFones sold out pretty quickly, even with the $40 price tag. What do you think? Would you use this iPhone case?
