Anyone else with asthma focus more on staying active and building lung capacity than just avoiding triggers? Curious what actually works

I've had asthma my whole life, viral induced. Had pneumonia multiple times and at this point I'm pretty sure I have some lung scarring. For a long time managing it meant just trying not to get sick and keeping my inhaler close.

What's actually made a difference is staying active and pushing my lung capacity rather than just playing defence. It feels counterintuitive but when I'm consistent with it I notice a real difference in how I feel day to day.

Curious if others think about it this way or if most people are mostly in avoidance mode. What does your actual routine look like? Do you track anything that's been genuinely useful, symptoms, triggers, medications?

Also wondering if anyone knows of an app built around this kind of thing. Not just a symptom logger or medication reminder, something that actually tries to help you improve over time. I've been thinking about things like VO2 max tracking to push lung capacity, trigger pattern recognition so you can actually get ahead of flares, and some kind of active guidance rather than just data entry. And if nothing like that exists, would you pay for it? Especially if the protocols were respirologist or sports medicine approved.
