Me and the wife do this twice a week, sometimes 3-4 times if there's not other stuff going on like bike rides or tennis matches or other exercise. We try to do some kind of exercise activity 6 days a week, but lifting you only need twice or maybe three times. First day of the week do the leg/core one and the other day do the upper body one. You will not get big doing this but you will get muscle endurance, you won't hurt yourself and you'll trigger your muscles to grow enough. The first time per week you hit each muscle group you get about 60-70% of the benefit, the second time you hit it you gain about 15-20% (way diminishing returns) and the third/fourth time you're overtraining and probably doing yourself a disservice.
