I don't know about you, but I see no reason that wouldn't apply to art! In the end, engaging in an activity like drawing is about connecting your mind to your arm and hand. You're creating a sense of coordination that is intended to produce a work of art. So, why not warm up that connection?
You don't have to do anything really fancy, but a few that I've learned from various artists include:
- Rays from a center point with the trick being that you always start from the center. This gets your hand moving in various directions.
- Circles and ovals, varying between clockwise and counter-clockwise. Get your wrist loose and moving.
- Boxes, squares, cylinders. Basic shapes.
- Contour line drawings. Don't lift your pencil, just draw some things in a continuous line.
- Basic shading, like a sphere.
- Hatching and cross-hatching.
Spend 15 or 20 minutes, basic doodle approach, and just connect the mind to the hand before you start into your actual drawing.
