Day Four/Five - I think I am getting the hang of this

So I have remarkably learned something new about myself the past two days. The positive side is that I am A LOT stronger than I thought I was. The negative side is I have been WASTING a lot of time not pushing myself to my fullest abilities.
Yesterday was madness. I am preop this week so I was up at 4:15am and at work by 5:30am. We were so busy that my 2pm clock out time became more like 4pm. I was so exhausted that I went straight to the gym in fear that if I allowed myself to go home, I would convince myself not to go. I had a cup of coffee and pep talked myself into giving my all in my workout. The energy was a little low at first but the trainer helped push me to my limits. We did a mixture of exercises focusing on the delts and through in a sprinkle of 200 meter sprints in there as well. I went to the military press station and grabbed the 15# dumbbells out of habit. Eric came over and graciously questioned my intentions with the chosen weight. He had me grab 25# dumbbells instead. I laughed at him as I felt I could barely carry them, let alone lift them over my head, but I was throughly surprised and actually kinda embarrassed that I was not only capable but was able to reach the required rep count and do it again the next set. Oopps. ;)
I then toted myself to the gym for a cardio session on the incline treadmill and some ab work. I got home at 8pm completely exhausted but feeling good that I had burned 800 calories during my workouts. I was excited to see that I had dropped 1.6 pounds this week and I am only .4 pounds away from my target weight loss goal for Sunday. Totally manageable.
 So tonight I made a point to push myself at the gym and at least keep trying the next weight range until I couldn't lift/push/pull it anymore. The result was a decent workout. I didn't have my gallon water bottle today and definitely noticed the difference in not hydrating well. I was also very annoyed by the amount of people at the gym this evening and the constant scouting for an open machine I was having to do to complete my workout. My abs feel awesome after some cable crunches though. I walked in the door again at 8pm. My husband and I had a little talk this past week and we developed an understanding that my focus the next 12 weeks includes: work, eating, working out and sleeping and that is all I have time for, literally. I am curious to see how I feel tomorrow seeing as I am counting down the days till my off day on Sunday.
