Updating your Facebook status each time you hit a new machine at the gym (SQUATS!) is just, I dunno… it’s not ideal, let’s put it that way. Put down your phone and pick up the Amiigo Sports Sensor Watch ($89 pre-order price), a new wearable sports sensor that promises to determine not only how much energy you’re spending, but also exactly what activity you’re engaged in, whether it’s JOGGING! or BENCH PRESSING! The wizards at MIT students are behind this watch, which also gathers vital info like HEART RA–sorry–heart rate, blood oxygen levels and skin temperature.
