For bassists — or really any musicians — Polish bassist Kinga Głyk has published a fantastic video showing part of her warm up routine:

She is using a violin exercise composed by Henry Schradiek and provides an accompanying PDF (bassists, watch out as it is in treble clef). Perhaps as valuable as sharing the exercise is the way she demonstrates it first at a slow tempo and then gradually increasing the metronome speed.

It’s a bit of a finger buster but also a brilliant resource.
