Set the stopwatch for 100 seconds, and then start squeezing your non-dominant hand (the hand that you don’t use for writing) open and closed as quickly as possible. If you have access to a ball, you can squeeze the ball with your non-dominant hand instead. During the activity, write down the number of squeezes you did at intervals of 10 seconds. You can ask a friend or family member to record the number of squeezes if that is easier. Keep a mental note of when your hand begins to feel tired. If you feel you can no longer continue to perform squeezes, stop the activity and write 0 next to the remaining readings. Fill in the table with your results.
