Mostly Kegel exercises are taught to women for various reasons as you can look up on the Internet.

Less well-known is that they can be quite important as well for men of older age, especially for prostate problems.[they will not solve all the problems]

I looked for descriptions or videos on the Internet and was quite surprised to see quite a bit of misleading instructions which will not help.

Therefore I am sending you this video link which describes in a very professional way how to do these exercises.
