I mostly work nights on alternate schedules from a start time of 2pm-5pm and a finish work time of 2am-4am. Is it best to workout at the beginning of my day or the end of my day? I love the gym at 2am there's no one there. Just the poor guy restacking everyones wieghts. Which I have always been confused about, returning your wieghts should be a part of your routine.
