UK-based DesirableBody stands out in today’s world where companies are announcing smaller, lighter and thinner cases. Made out of solid steel and rubber, the company’s ToneFone iPhone 5/5S case is heavy with a reason – these guys wants you to exercise all the time, even when making a phone call, texting or cyber-schmoozing while on the go.
Weighing in at either 1 kg (2.2 lbs) or 1.5 kg (3.3 lbs), the ToneFone effectively turns the iPhone into a small dumbbell to make every interaction with your beloved gadget a mini workout. Though you are also free to exercise when the phone is not in use.
The idea to have a dumbbell with you at all times is nice, but I’m not sure just how practical this case is. Nevertheless, the initial stock was sold out quickly, hinting us there’s demand for a product like this.
