This simple test can determine the strength of your core while revealing any potential underlying injuries to your spine and nervous system. Weakness on this test can provide early detection of underlying spinal weaknesses that you should know about.
You will need a flat surface and a watch with a second hand. Maintain a straight back throughout the test. Cheating on your body position may hurt you and give you false results. Try to complete all seven positions without rest or see how far you can get. Please refer to The 100 Year Lifestyle Workout book for pictures on pages 128-131 if you have any questions.
