If you regularly sit at your day job, be sure to make regular standing part of our routine. And, to help with the transition and on-going potential fatigue, invest in a quality standing mat that has good padding and a slope to it, like the AnthroDesk ErgoSlant mat.
Since many people sit in front of gadgets (like computers) for multiple hours a day, it’s important to incorporate standing into your routine. And if you are standing for 30 minutes (ideally) every hour, your feet, back, or legs may become tired. What can help is getting an anti-fatigue, cushioned mat. But shop around because not all of them are the same. The AnthroDesk ErgoSlant mat has a slope to it, in addition to it having very comfortable cushioning. It is so nice, my wife stole mine almost immediately!
