Standing desks are so passé. It’s time for squatting desks.

A USC-led study shows that squatting and kneeling may be important resting positions in human evolution—and even for modern human health.
Sitting for hours a day is linked to some health risks, including cardiovascular disease, likely because it involves low muscle activity and low muscle metabolism. However, these risks seem paradoxical. For humans, evolutionary pressures favor conserving energy. Spending a lot of time sitting would seem to accomplish that goal. So, why should sitting be so harmful?
The USC-led team has shown that resting postures used before the invention of chairs—like squatting and…
