If you want to do extra yoga exercises that's ok. Make sure you do the 5 rites exactly as shown in the original book first. They are energy exercises that balance and revive the energy centers. Any alterations may be detrimental.
I see on the internet U Tube Guru's showing how to do them and almost every time they are perverting them. They get the breathing backwards or substitute their own exercises.
