So if you're anything like me, you're not crazy about crunches. They're painful if you have a jutting-out tailbone, and unless you have ankle weights or a loyal buddy, it's hard to even do them right.
But I found a solution!!!
If your bathroom is laid out with a lot of room in front of the toilet, try this: Put a towel or rug on the floor in front of the toilet and lie on your back with your feet facing the toilet. Grip the bottom of the toilet with the soles of your feet, cross your arms over your chest and do crunches!! You won't have to worry about holding your feet down, so it's both easier and a lot more productive. It's kind of fun, too!
