Combine it with other commitments: walk the dog, do small-scale shopping (walk to the store and back), have a lunch break in a few minutes of walk from your office, etc.
This is, of course, most easily done in a proper walkable city. Elsewhere biking around could work, probably.
Even if you don't live in a particularly walkable area, about 5k of those steps would come naturally even to a young-ish sedentary person in the form of basic daily activities.
