There are some days when I don't have any time to work out. That means I just slept in in the morning through the time I scheduled for my work out, and I have a busy night with plans, so now I've left myself with no time and its my own gosh darn fault. So what do I do?
I make myself a little exercise chart in my notebook, and list out squats, lunges, jumping jacks, and anything else I can think of, and then do ten or 20 in the restroom every time I take a quick break at work. I just keep a running tally all day, and by 5 PM I've done a couple hundred of everything, and built up a sore little tushy and legs!
At least it's something! Tell me some more ideas! :)
