Any TV or other device is suitable as long as you can access the internet with a browser (e.g., Browser, Chrome, Firefox, Edge, Safari) and it is capable of playing YouTube videos.
Use the "Login on Another Device" interface, accessible from the menu of your already logged-in account, for example, on your smartphone.
This provides easy login when you want to access your account on a device where you do not have easy access to your email, and therefore cannot click the login link sent via email, e.g., in a Smart TV's browser. This way, you can easily access the Video Library, among other things, and work out on a big screen.
