At first, we just wanted to build a tool for ourselves that reminded us to do a couple of exercises to break our sedentary work habits. But then we thought it would be much more fun if more people could join us and we could all take a break together to do a mobility/strength exercise every now and then.
So we launched https://movefrequently.com/ : a world-wide initiative to perform a 1-minute mobility and strength exercise every 45 minutes. The tool has a universal timer so that everyone in the world using it will be presented with a simple exercise they can do in front of their computers.
We hacked this on Friday, but plan to give it some love and add features if people like it. Check it out and let us know what you think.
