We knew health and fitness gadgets were going to take up a big part of our CES 2013 coverage this year, but we've really been surprised - and oh so geekily excited - by the sheer volume of cool tech coming from Las Vegas that's set to really have a huge impact on the quantified self movement over the next 12 months.
Here's our pick of the top 10 gadgets from the show so far, but expect even more quirky, useful and even potentially life-saving pieces of tech to make an appearance as the week goes on.
BodyMedia Core 2
Bodymedia has brought out health and fitness tracking devices in the past, but they've always looked... well... really bloody ugly. Luckily the team has realised that aesthetics are important when you've got something strapped to your arm 24/7 with the Core 2, a tracking device that measures your sleep patterns, exercise intensity and the calories you've burned, as well as a range of other metrics. According to sources Bluetooth will soon be added, allowing seamless updating to your mobile phone, which is really a necessity now gadgets from the likes of Fitbit offer simple Bluetooth and wireless syncing.
