How do I do "Kegals"?

After having two kids, I began to have a constant urination problem. My kidney doctor suggested doing kegals to see if I could make my bladder stronger, etc. The best way she told me how to do them was every time I would go pee, stop it mid-stream a couple times and continue going until you're done. Sometimes if you have to go really bad it's hard but that is how I learned to do them. After a while, you get quicker at it hence making your muscles stronger down there. Once you start to do them while you pee, you're able to do them anytime you want because you get used to it.
