Asthma is a restriction

Same boat over here!

I'm a severe asthmatic. I also have been recently diagnosed with sarcoidosis in my lungs. I lift heavy weights 3-4 days and week and run 5 kms frequently on off days. I've found that Breo-ellipta has been the best medication for me. The key is finding a good respirologist and putting one foot in front of the other...

I was born with severe asthma. I walk on the treadmill, my fastest is 2.1...lol but I do it everyday and it has paid off. I also sitt down bike. You can do it!!!! Add me if you want.

Exercise isn't as essential to weight loss as calorie restriction. A couple years ago I was ending up in the hospital a couple times a week (due to asthma). I couldn't do anything for a long while except eat less and the weight did come off slowly, but it did come off.
Try using the rescue inhaler before doing any exercise, a lot of times that will retard the onset of exercise induced asthma as well.
It may be a slower road, but don't let asthma be your excuse to not lose weight. Every pound you lose will help your asthma as well.

I can relate. I use three inhalers daily for asthema but I still ride the seated ellipitical bike for 33 minutes at my gym four days a week and do strength training with weight machines as well. this also with haveing three total knee replacements in three years time frame and horrible allergies and with part of my left lung gone due to haveing supper bad case of pneumonia back in 2008. If you have to take thing slow then takwe them slow but work out some how in the long run your over all health will improve mine fineally is improveing.

Do what you can take it day by day abd be sure to have your backup inhaler like ventolin with you at all times especailly when working out.

I have asthma, but I ran cross country in college.
I learned to control my breathing and asthma attacks. When I am running and feeling like I can't control my breath anymore, I stop and control it again.

I'm a moderate asthmatic, and your nurse is right, exercise will help you.

The first thing I found when I started running was that I needed to understand what was breathlessness from being unfit and what was an asthma flare. As asthmatics, I think we can be very frightened (understandably!) of breathlessness, but some changes in breathing when running are normal and healthy. I'd recommend learning to be mindful of breathing - asthma impacts on the outbreath, so make sure you exhale fully when exercising. I rest a hand on my stomach every 5 breaths or so, to cue my body to fully exhale. Yoga is really useful for this as well.

I did the NHS C25K, but took it slowly and repeated several weeks until i felt comfortable with the increased demands on my lungs. In hindsight, I wish as a brand-new runner I'd know about the Galloway return from injury plan which starts with 5 seconds running/ 55 walking and builds up from there. I think that would have been a really good foundation to learn about breathlessness and recovery. I've followed this blog for a while, and found this post really useful (lifesawheeze.com/2011/03/galloway-method-and-asthma.html but the whole blog is useful for runners with asthma imo.

The other thing to be aware of is being mindful and conscious of your asthma without letting it rule you. There will be days when running is hard and you need to stop - my triggers are cold and pollen, so at some times of the year I know I need to take it easier. That doesn't mean slacking off, but maybe running for 1 min/walking for 1 or 2 minutes. You will still gain benefits from this slower pace.

Also, make sure you are having regular asthma reviews. If you are wheezing or feel tight chested during exercise, your asthma is not under control and you need a change of medication.
