But what to do when gyms are (mostly) closed, and the last thing you can think about when returning home is doing a workout? There are a couple of exercises you can do between calls: from shoulder raises, arm circles, and chair squats to calf raises, imaginary jump ropes, and wall push-ups, just to name a few. Afraid of getting weird looks from your coworkers? Walking during the day or climbing the stairs instead of using the elevator can work just as well.
