Go jogging every morning with a M-1 Garand !
Holy Moly, you are a stronger man than me, even when I was young and slim.

Given the parameters outlined, i.e., urban unrest, rioting etc., I'd just reach over to the end of the couch and pick up my M-1 Garand. I carry it every morning when jogging/walking. It is about as light and easy to manage as anyone could want. Stuff it full of some nice M-2 AP and put a roll of duck tape in your pocket. You'll be able to fix just about anything you might end up facing!
In fact, if the truth be told, for a actual urban meltdown type situation, a 15-22 and a backpack full of loaded magazines would also work real well. After all, in a urban environment distance is not going to be the problem. Most folks are not going to want to stand up and take a round. With a 15-22 you could put accurate fire onto a target and carry a pile of ammo while running, ducking or anything else that might be necessary. Of course the smart thing would be to take that 15-22 or whatever rifle you were going to use and go to ground, i.e., get out of sight and stay out of sight.
If the situation is something more like Red Dawn 2.0, then I'd grab the M-1 and all the ammo I could carry. Soon as I found a loose AK-47... I'd swap for it and resupply with ammo from folks who no longer needed it.
