Take a Stand
We all know that sitting too long at your desk can be unhealthy, leading to weight gain, repetitive-stress injuries, and poor posture. Using a height-adjustable standing desk has been shown to improve productivity and ward off the aches and pains that too much deskwork can cause. And sit-stand desks aren't all that expensive, either. You can find a good, manual model for about $300 or an electric standing desk for $700 or less. Be prepared to wait, though; demand for these desks is high because so many people are still working at home.
