If you want to lose weight, your Apple Watch can help you sustain healthy habits, but it can’t actually monitor your progress. For that you need to step onto scales.

Any scale will measure your weight, but that is only part of the story. Whether you are dieting or bulking up, it is just as important to keep track of your body fat. The trouble is, this is notoriously hard to measure accurately. As I discovered when I bought a new Withings Smart Body Analyzer, if you think you already know your body fat percentage, you are probably way off.

Apple Watch could become one of the most important devices you can shackle yourself to, so to amp up the Apple faithful into more heatlh-focused nerds, Apple has sent fitness guru Jay Blahnik on a special events tour in Australia, China and Japan.

Blahnik is touring the areas to talking to some of the biggest personal trainers about the intersection between fitness and technology. At the Apple Store in Sydney, Australian personal trainer Michelle Bridges sat down for an interview with Blahnik to talk about some of things she’s learned from filming the Australian version of The Biggest Loser.

IBM has announced a new alliance with Apple (among other companies) to utilize its acclaimed Watson artificial intelligence system to provide personalized insights regarding health data.

For those who don’t remember, Watson was the IBM A.I. which famously defeated two former winners on the gameshow Jeopardy! in 2011 to receive the first place prize of $1 million.

By linking up with Watson, Apple not only solidifies its existing relationship with IBM, but also gains a very powerful ally in its quest to revolutionize the way we think about mobile health with the Apple Watch and iOS 8 Health app.

One of the big selling points of wearable devices is that they will be able to help us keep track of various fitness metrics.

However, a new report claims smartphones are just as good (if not slightly better) at tracking physical activity as the most popular wearables on the market.

LAS VEGAS — Football in America is under attack after the revelation that concussions cause serious brain damage rocked the NFL. Youth participation has plummeted in the last two years but the folks at Linx have a new solution that will help parents keep track of when their kids are getting pounded too hard on the field.


The Linx IAS sports monitor is a tiny Bluetooth sensor athletes can wear in a skull cap or headband to keep track of every impact on the field, no matter if they’re playing football, lacrosse, soccer, hockey or pretty much any other contact sport.
