Daily vocal routine

Hi, I am wondering what daily exercises you would recommend to improve your overall singing. How much time you should spend on each exercise and what will they improve?

Here's a good 5-minute warmup: https://www.youtube.com/watch?v=DJc14znjETw

And a 12-minute warmup if you have more time: https://www.youtube.com/watch?v=LbL-xmTAswg

Both of the above videos have on-screen directions letting you know what each exercise is meant to train.

Here are a few articles to help you as well:
