Chris' personal trainer - his brother, Jonathan Sims, joins the show to talk about fitness. No, not fitness whole enchilada in your mouth, they talk about functional movement, the social construction of fitness, and separating fact from fiction in an increasingly commodified field. Jonathan breaks down short term and long term issues for fitness that archaeologists need to think about - especially if you want to avoid destroying your knees, shoulders, and back after a career in the field.
