Tonight I made the decision to buy an exercise ball on the way home. I also decided to try the 30 minute workout on the included DVD. I made it through 20 minutes of it actually got my heart rate up more than I expected it would. It seemed like the balance involved really will help my core strength.
Oh, and I didn't stop at 20 minutes due to fatigue, or lack of will, or anything like that. My 13-month-old daughter brought me a book she wanted me to read with her. I decided to go with the far more worthwhile option.
Every decision matters.
