Not that I'm always good about it, but like the Nike commercial says, "Just Do It."
I did squats in the shower this morning. I did crunches waiting for the boys to fall asleep (in the dark with the dog nosing me because she decided she did want to go back upstairs). I justified skipping swimming this morning because I wanted to get a free latte at work.
There's no perfect time to start working out. There's no perfect workout. It takes about 30 days to form a pattern and 90 days to form a habit. I'd love to go swimming more, but I think I need to think smaller. Starting tomorrow (it's a little late for today), I'm going to try really really hard to move for 15 minutes. Whether it's walking or swimming or jumping up and down with the kids (have you noticed if they haven't gotten enough exercise, they start doing laps around the house just before dinner time?), I'm going to do it. Wish me luck.
