Advice, please!

I'm new to fitness. I have access to an elliptical machine and I would love to try yoga.

Does anyone have any tips on where a beginner should start the different settings on the elliptical? Such as incline, speed, etc.

Should I do yoga before or after using the elliptical?

Do I do these things every day of the week?

What are some good healthy snacking tips?

Does Netflix have any good yoga shows to use as a guide?

Any and all help is much appreciated!
