In an ideal world:
Up at 4:50 on Tues/Thurs, get ready and dressed and go to gym, wait outside at 5:15 am, opens at 5:30 am, get my lane in the pool, swim 45 minutes. Shower, go home, breakfast, out the door at 7:15 am, work by 7:30 am.
Up at 5:30 am on MWF, get ready and dressed, pop in a workout DVD, finish by 6:30 am (or earlier, ideally before the younger child wakes up, because he won't let me work out). Shower, etc. etc. work by 7:30.
My world is not ideal. My toddler has been waking us up often in the middle of the night. I also have insomnia. So after being up for a couple of hours - whether it's my pool day or not, I generally cannot wake up until 6:30 am, and then I am "catching up" the next night. So each night of wakeups results in two lost workouts, generally.
This morning I woke up at 6 am but toddler got up at 6:10. Still managed 10 minutes of pushups, squats and crunches before showering (hey, you take what you can!)
