This book has been approved by TWiEA - The World Isometric Exercise Association (www.TWiEA.com). In the words of my old friend and mentor, the great Zig Ziglar who was one of the greatest-ever motivational speakers, "Logic will not change a feeling or emotion, only a physical action will" and today, these words are more important than ever before. Our mental health is every bit as important as our physical health, especially in the wake of the enforced self-isolation of 2020. In the early Spring of 2020, the world changed forever. Almost overnight, millions of people around the world were being forced to self-isolate. This was challenging enough if one had company, however, millions around the world live alone so for them it was worse. Self-isolation meant riding the peaks and troughs, the emotional twists and turns as spirits rise and fall as feelings change, and all too often distort. Even though we are now thankfully leaving that dreadful period behind us, many who are still comparatively isolated for whatever reason suffer a rollercoaster of emotional highs and lows. Research has shown that exercise can help to beat depression and anxiety and some studies have even found that exercise can be equal to or often better than medication. How can you exercise if you have little or no money, little or no space, little or no motivation, and no idea about how to exercise? The 70 Second Difference(TM) is a protocol based upon the premise that 70 seconds of consecutive exercise time is the time needed to perform a 10-exercise total-body workout routine using the scientifically-proven isometric exercise system with each individual exercise lasting just 7 seconds. In the exercise section, there are arrows clearly showing the direction in which the force should be applied. I will finish by remembering my friend Zig Ziglar once again with another of his more fitting, "You are what you are because of what goes into your mind" so help to make the input positive. NOTE: Feel Better In 70 Seconds(TM) is based on the same essential 10-exercise routine of The Zero-Footprint Lockdown Workout(TM), and both are based on The 70 Second Difference which is a greatly expanded book with a lot of valuable information about exercise and nutrition. NOTE: The authors, Brian Sterling-Vete and Helen Renée Wuorio are exercise specialists who have worked closely with the NHS Innovation Team at the Greater Manchester Mental Health NHS Foundation Trust on two major isometric exercise trials during 2020. This was an outstanding success and they are now moving into a third much bigger trial before looking towards an expansion into more sectors of the NHS across the UK. TWiEA will be involved to conduct isometric exercise instructor training programmes for key NHS staff.
