Your fitness doesn’t need to suffer just because you’re stuck indoors during the coronavirus quarantine. In fact, now is the ideal time to start working on your six-pack. The lockdown won’t last forever. If you put in the work now, you’ll be looking like a ripped ex-con by the time we’re all allowed out again.

This post covers everything you need to know to build rock-hard abs. We’ll dispel a couple of myths that stop you from blasting your belly fat. And, in the video, I’ll show you the two essential types of core exercise you need to know.

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.

If you’re anything like me, you pretty much spend all of your day clicking. Clicking a mouse. Clicking a trackpad. Clicking a keyboard. And yet, despite all of that physical exertion, I’m still somehow a fatass. How can that be? Luckily, some scientists have looked into the problem, and figured out the answer: I’m just not clicking enough.

Out of the box, the iHealth HS3 Wireless Bluetooth Scale ($70) is somewhat impressive. With its digital (albeit not backlit) display and snazzy looking-glass top, this is a scale that will at least look spiffy in your bathroom when company is over. Even in the box, the scale makes a good case for gadget adoption: It promises to keep track of your weight, calories and exercise easily using only the scale itself and an accompanying app that can be used on your iPhone or iPad. Technically, the iHealth Scale does do that, but there are a few kinks that make this product’s promises fall flat.

Despite all our 21st-century technical wizardry, one of the easiest and least expensive ways to get a very basic idea of physical health is through a metric that’s been used for a very long time: body weight.

The Withings WiFi Body Scale ($160) takes this concept to the next level in many ways, including allowing you access to all your data on a gorgeously designed iOS app. It also adds an even more important metric, body fat percentage, and goes a long way to erasing many of the pitfalls using a simple scale can lead to — and it does this all while remaining incredibly easy to use. In fact, it might be the most effective tool I’ve used to keep healthy.
