The intervention will include all of the following exercises: 1. Breathing Exercises: * Breathing control: • Start with the breathing exercises at least twice a day, and increase to 4-6 times a day • Breathe in and out gently through the nose if possible. * If the breath is out through the mouth, the participant will instruct to purse their lips as if they are blowing out a candle * Attempt to release any tension in the body with each exhalation * Gradually try to make the breaths slower * Each participant will instruct to close their eyes to help focus on breathing and to relax * Deep breathing exercises * The participant will be instructed to take long, slow, and deep breaths through their nose and keep their chest and shoulders relaxed. * Breathe out gently and relax, like a sigh. * They should do three-five deep breaths. * Repeat for two minutes several times a day. * Huffing • A huff is exhaled through an open mouth and throat instead of coughing. It helps move sputum up the participants' airways so they can clear it in a controlled way. * To "huff," they must squeeze air quickly from their lungs through their open mouth and throat as if trying to mist up a mirror or glasses. * Use their abdominal muscles to assist them in squeezing out the air, but do not exert so much force that it causes wheezing or chest tightness. * If huffing clears their sputum, they should not need to cough. They should only cough if the sputum can clear quickly. * The participants should continue the breathing exercises for about 10 minutes, ideally until their chest feels clear of sputum. 2. Strengthening Exercises \- To help restore muscle strength and increase endurance for 3 minutes daily. * Standing heel raise: hold on a chair, integrate arms reaching overhead when on toes.
