Right now it's very easy to practice social distancing while getting a good workout cycling, running, hiking, skiing, etc.
Being outdoors is good for your health, especially when the sun is out. Exercise is good for your immune system. It's also good for your mood and for reducing anxiety; these are going to be a struggle for many people.
You don't have to spend $500 on home gym equipment to stay active through this. If you have a pair of shoes you're golden.
Finally, when the weather doesn't cooperate, dress for it as well as you can, do your thing, then come home, take a hot shower, put fresh clothes on, and you'll feel brand new.
