Step out - backwards! The Chinese have a saying that 100 steps backwards are worth 1000 steps forward - and they might be onto something! It may look bizarre to onlookers, but Michael delves into the research and finds some surprising benefits. It’s been used for decades in rehabilitative physical therapy, and recent research reveals that it could even boost memory - by giving your brain a workout! Michael also speaks to biomechanics expert and champion of backwards walking, Professor Janet Dufek from the University of Nevada, Las Vegas, whose research suggests that walking backwards could help with lower back pain. They discuss why walking backwards is so beneficial for our muscles and how to do it safely. Volunteer Nina takes her daughter with her for a backward stroll - and gets a laugh out of it!
