  • cuts your risk of chronic illnesses,

  • bolsters your immune system, strengthens your bones, and reduces chronic pain?

  • Strength training.

  • And that's not even a full list of all the benefits.

  • To help you get started building muscle, we created a newsletter series.

  • No experience necessary to get going.

  • sign up at npr.org slash stronger or find the link in the episode description.

  • You're listening to LifeKit from NPR.

  • There's something we don't talk about much on LifeKit and that's weight loss.

  • There are a lot of reasons for that.

  • One is it feels like conversations around health and fitness can focus too much on losing weight.

  • when our physical health is more complicated than that.

  • Also, this show is about a life well-lived,

  • and there's so much more to that than how many pounds you weigh or how your body looks.

  • That said, we felt like this was the time to talk about it again.

  • Losing weight is a very common New Year's resolution,

  • but it's complicated and there are a lot of misconceptions about it.
