Introduction

Michael adds a plank into his exercise routine and is surprised to learn of its huge benefits to our physical health. Dr Jamie O'Driscoll, a Reader of Cardiovascular Physiology at Canterbury Christ Church University, reveals how the plank is a form of isometric exercise, where muscles are held still, neither stretching nor contracting. Jamie shares his research that found these exercises, including the plank and the wall-squat, could massively reduce our blood pressure. Michael also explores how the plank can even be better than crunches of sit ups for your abs and core muscles. Our volunteer Penelope takes on the plank, excited to learn that this small addition to her fitness regime could wield great results.
