Yes, but IMO, why use weights if you aren't going to use a weight that's challenging enough, which is what you have to do to be able to do circuits every day.
And doing circuits every day doesn't leave you any time for heavier weight training (which, even if you aren't looking to build muscle, is important for everyday strength, for having a reserve of strength as you grow older, for making everyday tasks easier, and for bone strength).
I've also used SS, but found that while the idea works for lower body, it can be tough on the smaller joints of the upper body (elbows and shoulders), perhaps especially her double-time reps.
I would not work upper body with weights every day, but YMMV.
