Exercise is healthy. That is common knowledge. But just how rigorous should that exercise be in order to really impact a person’s fitness level? And, if you sit all day at a desk, but still manage to get out and exercise, does that negate your six, seven, or eight hours of sedentary behavior?
These were the sort of questions Matthew Nayor and his team at Boston University School of Medicine set out to answer in the largest study to date aimed at understanding the relationship between regular physical activity and a person’s physical fitness.
