Just don't go exploring ffs at the moment.
There are reasons why daily exercise is just daily exercise. It's so you don't fall through a rotten floor, cut yourself on a sharp edge, have a roof collapse on you, be probed by aliens, etc.
It's not worth the risk or then the additional risk you'd then put onto the emergency services, somewhere like this won't look any better or worse after the lock down has ended, even if it did you should not be doing it at the moment.
