Description: On today’s special show, Mark Sisson and Katy Bowman discuss their exciting joint project, “Don’t Just Sit There,” which is a comprehensive multimedia educational course designed to help people overcome one of the major health hazards of modern life: prolonged sedentary periods that compromise your health at the cellular level. Katy is a biomechanist (someone who studies living structures like the human body), author, and popular blogger at KatySays.com. Her focus is on how movement and variability are the keys to a healthy work environment. It turns out that true movement variability at work requires more than simply transitioning from a sitting to standing position at a standup workstation. And it’s not just about assuming the correct ergonomic positions at your keyboards, either. Anytime you have prolonged stillness, you are putting undesirable “loads” upon your cells that can lead to pain, dysfunction, and disease. This includes your eyes gazing at a computer screen at a fixed distance for hours.
