Sometimes I feel like Jekyll and Hyde

Yesterday, I worked out for a half hour on the elliptical.
Today, I worked out for a half hour on the elliptical and one half hour on the treadmill (whilst reading a book, of course) and I'm going to go and bash some walls in at my friends new fixer upper home!!!
Yes, you noticed: Two days ago, I did not work out. I had the intentions of going on a walk because it was lovely outside, but after my tax test and less than four hours of sleep, I could barely do anything... (shrug of the shoulders)
