There has been so much recently about the dangers of the sedentary life, but this book joins the dots in a very interesting way. Vernikos was involved in Space projets at NASA and she points out how the impact of weightlessness in space are actually the same impacts - but amplified and condensed - that flow from spending so much time sitting down.
Sitting is our way of avoiding the challenges, the exercise, that are properly delivered by gravity.
Her prescription is expected - move more - but it is the language that is interesting and motivating - the idea of doing more Gravity Exercises.
She points to some good research too. For example it is not just about spending time stood up....but the repeating acts of standing that are important. It reminds me of the floor exercises ideas that I pointed to a few weeks ago.
