How to do the test

Reach one hand over its shoulder and the other up the middle of the back. Bring the middle fingers toward each other without forcing the movement. Measure the gap or overlap.

Understanding your result

Fingertips meeting is 0. Record a gap as a negative number and an overlap as a positive number. The ranges below are in inches.
