How to get physically fit during the pandemic or for anytime?
Spend about sixty dollars on a 6.5-lb Health Hoops weighted hula hoop with large knobs on the inside, somewhat similar to a reverse circular saw blade. Use it four times/week for about twenty-thirty minutes accompanied by fast, loud, work-out music and you should lose weight, get thinner, eliminate lower back issues, increase mid-body strength, stomach, abs, and core strength. 20-minutes is a very tough hula-hoop workout, at first.
It looks a wee bit odd when using it but so what. ....

.... looks like hula-hooping with a large, wide, heavy hula hoop.
Go to Amazon or Ebay and enter 'Health Hoop Korean' and it will add 25-years to your life ......... guaranteed .....

..... plus it makes it much easier to go for long walks or hikes while carrying a 10-15-lb day pack.
Now, back to those $164.88 floating water mats ....

..... before this thread gets locked up! ....

..... is good for using the water mats as well. ....
