I exercise and work at the same time for 45 minutes a day. I installed a workstation on my treadmill, but unlike most worker's treadmills I use it for aerobic exercise, not a slow walk. I can type because I set the treadmill on maximum incline and walk at less than 3 mph. So in effect I am using it like a stair-stepper. I've been doing this every day for 15 years and I couldn't imagine stopping.
