1. CYCLE OR WALK TO WORK. This doesn’t need to be everyday but once or twice a week is better than nothing.
2. If you drive to work, park your car a few blocks away and walk the rest of the distance
3. If you are on public transport stand instead of sitting and transfer your weight onto one leg for a minute or two, then the other. If its safe to do so rest your hand on a rail rather than a tight grip and switch your core muscles on to stay steady. Also get off a few stops earlier and walk the rest of the way!
