Social distancing

So I live in a city that is almost on lock down. I mean almost everywhere is closed, schools are cancelled, we’ve been asked to social distance ourselves from other etc. Well my husband is a personal trainer so when his gym closed he was devestated. Working out is a huge part of him so instead of staying home these past few days he’s been going to workout with his friends at their houses. I have no issue with it but I’m not sure, is it wise of him to be doing that? I just keep seeing all these posts about not having play dates for your kids and no having friends over for coffee etc. I’ve been stuck at home with my 8 year old and 8 month old and we’ve been going a little stir crazy. It’s been cold and snowy out so we are t even able to go outside for long. This whole situation just seems like a bad dream. It’s crazy.

Anyway my question is is my husband being smart by going to friends places to workout? I workout at home and we have the equipment here but he refuses to workout here.
