The millions of people with time on their hands can use that extra time to stay fit. We have noticed a big increase of runners and walkers in our neighborhood. We are fortunate to live in California, where the weather is usually good, whereas people living in areas with poor weather need to do their exercising indoors. Those who already disciplined to do exercises like Pilates or Yoga may not need any extra gear, but others need equipment such as stationary bicycles. People who are overweight or obese have a greater chance of getting ill from Covid-19.
Even our pets are overweight these days!
