Hello, @lilianna. I would say that I use the Aerobika for a maximum of 15 minutes, usually 10.

I do 3 smaller inhales with holding and then breathing out, followed by three moderate inhales with holding and then breathing out, and then three deep inhaled with holding and then breathing out. I do this first in the sitting position, then lying down on the bed on my right side with bottom elevated with a wedge pillow. Then I shift to a diagonal position and repeat, followed by on my back with repeat, and finally on my left side with repeat. Sometimes I will stand on the floor and bend over, supporting myself on something, and repeat in that position.

I also walk briskly two miles each day, followed by up and down a set of 24 stairs four times.

I also sometimes do deep breathing with holds and exhaling during the day.

One thing that really helps me is to drink hot beverages because they help to loosen mucus. I take a time released Guaifenesin morning and evening along with a 600 mg NAC morning and evening.

Another thing I do daily is to grate a garlic clove over a couple of tsp dried thyme and cover with olive oil. I let it sit for a while, and then I use a good bread to mop it up. It burns the mouth a little, but it helps to open my airways and to keep infections away. I believe it may also help to prevent fungal infections because garlic is known for that. That is just my personal routine!
