The few times I can get myself to do workouts during work stretches, it’s before work. I’m 41 and have younger coworkers that hit the gym after work pretty regularly. I work 12.5 hr night shifts as a critical care RN and find anything but endurance or recovery workouts really hard to do.
It takes months to get use to night shift. Also if you are doing it 5 nights a week you need to try and stay close to that schedule on the other days. I flip back and forth but only 4 shifts and 2 shifts in a row on a repeating pattern.
