These smart glasses became my erratic personal trainer


As I've written before, JINS' smartglasses are unassuming and normal-looking. In Japan, there are several frame styles to chose from (including the aforementioned running version).

USATODAY - Tech Top Stories

The best 7-minute workouts on the planet are the ones you'll actually do. This is what I know for sure after testing out more than 30 of them over the past few months.

With or without weight, it's widely regarded as the best exercise you can do. But one that's easy to get a little bit wrong and ruin all those benefits. So here's Kaia Health's Perfect Squat Challenge app, developed with input from both physiotherapists and sport scientists to help you nail the form. In the company's press release, Maximilian Strobel, Head of Kaia Health's AI Lab said: "Breakthroughs in AI-powered motion tracking and correction technology mean that everyone now has access to a virtual personal trainer and physiotherapist on their iPhone -- and can perfect exercises such as the squat." "Perfect" is a brave word choice -- debate over ideal squat form often reaches yanny-or-laurel levels -- but the app is, still, rather remarkable.

Netflix cuts out the chill with an integrated personal trainer

The Netflix Personal Trainer has some of the features you might find in its flesh-and-blood counterpart, and some you definitely won't.

If you start slowing down, "your selected Netflix character will deliver motivational words to keep you going."
