The Powerbeats Pro 2 are a great little set of headphones, with lots of smart and convenient features. But what really made me want to check them out was the heart rate feature. Would it work as well as advertised?

The Apple Watch—and other smartwatches—are designed to be worn on your wrist. But why not wear it elsewhere? I’ve worn an Apple Watch on my ankle to keep it out of the way during kettlebell workouts, and that’s also a common placement for people who walk while they work, or who have a job or hobby that isn’t compatible with constant watch-wearing. So how do you do this, why might you do this, and is the data really just as accurate? Here’s what you need to know.

Traditionally, eggs have been one of the cheapest sources of protein, but bird flu and inflation are changing the equation. Here are your other best options for inexpensive protein, when the gorcery bills are getting too high.

If your Garmin watch is showing a blue triangle, you’re not alone—users of Forerunner, Fenix, and Epix watches have been reporting this issue since January 28, and Garmin is looking into it. There’s now an official fix.

A recent study found that some smartwatch bands contain perfluorohexanoic acid, one of the “forever chemicals” that is suspected of contributing to health issues. But these chemicals, also called PFAS, aren’t in all watch bands—here's how to avoid them.

I’ve tested tons of health and fitness apps over the years—some to write about, some because I was curious, and some because they are genuinely useful to me. Here is my Fitness App Hall of Fame: the fitness apps that I use the most, and the ones that I think are the most useful for everybody. All of these apps are available on both iOS and Android.

The “Couch to 5K” program has gotten tons of people started with running. But the plan also has its drawbacks, and it’s not the only way to become a runner. Here’s what you should know before you give it a try—especially if you’ve already started and feel like it’s not working for you.

The new year is a great time for nerds like me. If you’re a sucker for the joy of a new training journal, the fresh promise of a program you’ll check off one day at a time, or even (admit it) the kid who really loved filling in bubbles with a number two pencil, you’ll enjoy this bubble-style calendar that a generous Redditor posts each year.

My Garmin watch tells me that I have 21 hours until I’ve fully recovered from the workout I did earlier today. It wasn’t even a hard workout, but I’ve come to expect long recovery estimates from Garmin—and I won't let this number stop me from going on an easy run in the morning. The recovery time doesn’t mean what you might think it mean.
