There are a few easy methods to stream the app on your phone or tablet to your TV! 

1) AppleTV App

If you have an AppleTV, simply download The Fitness App by Jillian Michaels in the App Store app to your Apple TV and start streaming unlimited workouts on the big screen. You also can mirror your phone directly to the AppleTV if you want to stream the workout directly from your phone.

2) Samsung TV App

If you have a 2018 or newer Samsung Smart TV, search for Jillian Michaels Fitness App in the Samsung App Store, download it to your TV, and start streaming! 

3) For newer Android devices, swipe down from the top of your screen to find the Cast button which will allow you to stream directly to your TV. For older devices, you'll need to install an app called Google Home to stream it.
