Are the exercises difficult?
That's another matter. Yes, they are quite difficult and not very pleasant. If you really enjoy doing them, you can know that you are doing them wrong. But that is to be exepected. You will need to work in order to improve your health. It's much easier to take a pill or a puff of your bronchodilator. It takes effort to do any kind of exercises. But your effort will be rewarded with the most prescious gift of all - good health. If you are not prepared to work in order to earn good health, exit now.
