Doing single-foot balance work like this is a great way to not only maintain (or improve) you balance but it is also a great way to strengthen those little stabilizer muscles around our ankles, knees and hips.
I suggest doing this routine a few times during the workday when you need a break. One side benefit of a meditative movement like this is that it helps you wake up, focus, and regain your concentration.
