Stretching exercises.

At the dry stone walling workshop in Redwood City yesterday students were taught the importance of warming up and stretching before attempting to move a lot of rocks all day. John Scott showed us an exercise that helped loosen up the back muscles and enable people to stay flexible. 

Throughstones are added every four feet along the wall at knee height.

In just the same way way stone walls are built to be able to yield to different natural forces, people need to ensure that their joints can flex and move during periods of stress.
