Our expert says:
It's great for now. 30 minutes at the start is tough, most people would struggle, especially coming from doing almost nothing for maybe a long time. So if 30 min is the ceiling, then so be it and just stay there while you get fitter.
Eventually, that will happen - you'll either run faster and further in those 30 minutes, or you'll start to feel good at the end. And that's when you add to it, up to 35, then 40 and so on.
I think given your situation, exercise will help, but what will really help is if you find a goal - maybe decide that you're going to run a 10km race in 3 months, or something like that. Find friends to do it with you, added motivation, that sort of thing.
