We use the Pamela Reif instruction videos. We got lucky: our gym rented out equipment on the last day they were open, we got some kettlebells, jumping ropes. (No money exchanged, they keep charging the monthly gym cost).

Down dog is really good for yoga and it's free until the end of the month I believe. https://www.downdogapp.com/
I recommend 5BX. It's simple, requires no equipment, doesn't take long and works. It's often looked down on because all sorts of other advanced programs have come along. But if you need something you can do anywhere this is a simple plan and it's well laid out.
