Probably the biggest problem with starting to work out or do any excersises is the motivation. I recommend you to find some colleagues to join you (or you join them) in running or jogging. It is probably the most efifcient method to get motvated in the beginnings. When I was beginning, running with someone else made me manage to do a distance like 30-50% longer than if I would have ran on my own. That works nevertheless of the sport, I guess, be it in working out, running or anything.
If you prefer to begin on your own, check out some tracking apps, (like in
this topic). getting notified of the results, and seeing improvements helps a lot
That's just a short text about how to begin for you
I do run and do push-ups almost everyday. That does not require too much time and makes one feel a lot better!
