According to Cornell University’s ergonomics experts, standing all day isn’t better than sitting all day. Instead, we should do both:
“Sit to do computer work. Sit using a height-adjustable, downward titling keyboard tray for the best work posture, then every 20 minutes stand for 2 minutes AND MOVE. The absolute time isn’t critical but about every 20-30 minutes take a posture break and move for a couple of minutes. Simply standing is insufficient.”
That’s exactly what I do, and I use Break Time to prompt me. Now I can stop feeling guilty for not having a standing desk.
