Shoulder workout and studying

Spent most of today studying for Wednesday's CB test. I only managed to finish half of my workout  today because I felt so unbelievably drained. I don't know why, but I have a good guess it has something to do with stress and study. I'll try and do arms with abs later on in the week to make up for it.
