Get your heart rate up, multiple times a day

“Stairs can be your cardiovascular best friend,” Ms. Johnson said. If you have access to stairs in your home or apartment, going up and down those stairs is a great way to get your blood pumping.

For a great full-body home workout, you can do an entire circuit sequence for up to 30 to 45 minutes. If you are working movement into your daily tasks, she also suggests creating more activity while doing things you already need to get done. For example, if you’re carrying laundry upstairs, take an extra lap or two up and down the stairs to work in extra steps. “Every little bit counts toward a healthier you,” Ms. Johnson said.

Dr. I-Min Lee, a professor of medicine at Harvard Medical School, recommends simple fitness exercises like marching in place, doing jumping jacks or jogging in place with high knees.

Get out and walk, even for just 15 minutes

“As long as the public health practitioners haven’t suggested a total lockdown, as long as you’re able to maintain a reasonable amount of distance and you’re being good about hand hygiene and especially if you’re staying completely home if you’re having any signs of illness, then getting outside for a walk is good,” Dr. Buhr said. “It clears your mind, and it keeps you active.”

Everyone should all aim for 150 minutes of physical activity every week, he said, but the amount of time you walk each day can vary. What counts is that you’re moving your body.

Stretch it out for at least 30 seconds

Stretching is essential, Dr. Lee said, because it helps maintain flexibility. Here are six simple barre stretches you can do in your home or outside. Ms. Johnson also likes the warrior pose stretch and the prayer stretch, which targets the lower back. In a Zoom meeting? Stretch right now.
