I'm doing something similar. In normal times, I go to the gym every day or two and work out for an hour and a quarter. Since I'm now home all day, I've been doing bodyweight and dumbbell workouts next to my desk for fifteen or twenty minutes several times a day. They break up the monotony and refresh my mind for the next round of work. I also fit in extra exercise during Zoom meetings that I only need to listen to.

The result has been that I am staying in shape despite being indoors all day. The staggered workouts may be more effective at building muscle than my usual gym sessions, too.

The greatest benefit of the exercise, though, is the mood elevation.
