What is the correct method of doing kapalbathi pranayam. Does it help in toning the abdominal region? How long should it be done to tone the abdomen? Thank you.

The correct way to do Kapalbhati has to be learned from a teacher, or another way could be to get a DVD and practice with it. We have several such DVD's To answere your other question , YES Kapalbhati can tone your stomach, it is like doing crunches sitting down. Start your practice right by learning it the right way and you will have great results !!!
