Bob King, CEO of Humanscale, argues that bad posture is a design problem, not a discipline problem. He explains that sitting still, not sitting itself, is the primary health risk, as it disengages muscles and stresses the spine. The key to a healthier workday is frequent movement, such as a five-minute walk every 30 minutes, which can significantly reduce blood sugar spikes. King advocates for intuitive ergonomic tools, like chairs that use the user's weight for automatic adjustment, to eliminate the need for willpower. He also highlights the dangers of off-gassing from office furniture, which can release carcinogens, and advocates for ingredient labels on products. An optimal workday includes a sit-stand desk, a chair that encourages movement, and attention to indoor air quality.
