You absolutely need to prioritize getting 30-60 mins of exercise at least 5 times per week. Block out time on your work calendar if you have to. The cognitive / health / mood benefits will make up for the lost time.

A home gym setup will save you the 30-40 mins to and from the gym. Barring space for any equipment / weights some exercise bands and a yoga mat will do. App based fitness classes such as AppleFitness+ also make it much much easier to program your workouts.
