Building lung health and Endurance through Exercise

Hi all,
So I had a real win a couple of days ago, which I would like to share with you that have EIA. Briefly, back about a year ago when I was first diagnosed with allergic asthma exerberated by exercise (as well as high pollen counts and dusty conditions), it really threw a spanner in the works of my aspirations of getting fit again after a few years layoff and losing the extra 10 kg, I had put on. Every time I walked too fast, climbed stairs or danced at a function I felt breathless, my chest closed up and I seriously wondered how I could possibly have become so unfit while still maintaining a fairly healthy lifestyle. Fast forward to the middle of lockdown and no organized exercise classes, and our trainer decided to start circuit training on the local country club soccer field while the gyms were closed. Every morning I puffed and panted my way through the hour with just a couple of puffs of my bronchodilator inhaler that I had used intermittently on very bad allergy days for the last few years. Eventually I went to the doctor and was officially diagnosed with asthma, prescribed a maintenance inhaler and given proper instruction on the use of my rescue inhaler before and during exercise. And so I thought my breathless, difficult exercise sessions would be a thing of the past. It very quickly dawned on me (and my trainer), once we were able to get back to the gym, that was not to be, and so began an ongoing rollercoaster of up and down asthma days, hyperventilation episodes and rushing to get me to the doctor and be given oxygen after a half hour spin class. BUT in all these ups and downs, which still frustrate me and make me dispondent at times, and the ongoing support of my trainer, who by now, knows the drill, and slowly slowly my endurance is building up and I can run for 10 km per hour on the treadmill for a minute, after a slow steady warm up, and just this Friday, I maintained through an hour spin class, even managed to do a minute spint cycle, with my trainer standing close by in case I needed her, and when I gave her the thumbs up, I was fine, she and my spin class gave me a round of applause. I have to tell you, it felt so great. So the moral of my story is to just not give up. Surround yourself people who support you and educate them on our condition. Working with an experienced trainer really helps, and I am blessed to have one, and always train with someone if you plan to do a harder workout. Just knowing you have someone who has your back if things go sideways helps to build confidence which goes a long way to helping you achieve your fitness goals.
