The authors, Brian Sterling-Vete and Helen Renée Wuorio, worked closely with the NHS Innovation Team to create a practical and effective system suitable for virtually anyone, even if they wish to exercise discretely while at work to save valuable after-work time.

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.

Our mental health is just as important as our physical health, especially after the enforced self-isolation from 2020 onward.

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 worldwide live alone, so it was worse for them.

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 is a protocol based on the premise that 70 seconds of consecutive exercise time is needed to perform a 10-exercise total-body workout routine using the scientifically-proven isometric exercise system with each exercise lasting just 7 seconds.

In the exercise section, arrows clearly show the direction in which the force should be applied.

I will finish by remembering my friend Zig Ziglar again with another of his more fitting sayings, "You are what you are because of what goes into your mind", so help make the input positive.
