You can do zumba at home, MK. Lots of zumba vids on YouTube - I've downloaded some and plan to get more, so that I have a wider selection of songs/ dances. There are also TaeBo vids on YT.
I'd prefer to take walks/runs, but as it's not advisable now bcos of lockdown in my area, it's time to get zumba-ing again.
Hope you & your family are safe & healthy!
