Standing spiccato (playing spiccato using repeated up or down bows) is a forearm movement supported by hand and finger action.
Practise the action on an open string, making sure it is regular and clear.
Just as with spiccato you can change the character of the stroke by varying its length and height, although usually when using it in the repertoire aim for a long enough stroke for resonance.
The excerpt is from "Catch Me If You Can" by Mary Cohen.
