But I may decide to dance with a 15oz can of food in either hand, so my arms have a little more heft at the ends for strengthening purposes. Good idea y/n?
In terms of muscle physiology, probably not the most effective way of strengthening, because that generally happens at the "low reps heavy weight" end of the spectrum (whatever "heavy" is for you, but we'd be talking something you can only lift for 1 to 10 reps in a row, not, say, 30-40 reps). If you can dance with it doing the same sort of arm moves for 15 minutes straight, it'll be working muscular endurance, not strength.
However, that endurance might still be a useful goal for you!
And personally, I am all in favour of including random physical experiments in my dancing time. You could play with lots of different moves and see what the cans feel like. Just don't be afraid to dump them if it feels too much, gets boring, or your shoulders/any other joints feel tweaky, etc..
