Life Kit is excited to bring you more episodes but we're making some changes to how we organize things. Starting in the new year, this three-part guide will disappear, but all of the episodes will still be available — they are just moving to our main Life Kit feed. Search your podcast app for Life Kit from NPR and subscribe so you never miss an episode.

Based on your feedback, we've created new ways to listen to Life Kit. If you never want to miss an episode, subscribe to Life Kit: All Guides. We also divided our guides by subject — health, money and parenting - and more to come in the future — so you can subscribe to only the topics you want to learn about.

Take advantage of Life Kit's other useful guides to help you get it together. Also, please take our survey! It's at npr.org/lifekitsurvey. It'll help make the show even better.

Falling off the exercise wagon more than you'd like? These strategies, based on economics and the science of habit formation, can help. Plus, you get to binge-watch TV.

A lot of us love to hate exercise. In these episodes, we talk to the experts about how to think differently about exercise so that it fits right into your life, for good.
