I used to have asthma but it still feels like it might've returned. Running is difficult because I cant breathe properly and its extremely painful. Sometimes I can taste blood. That's why I usually avoid exercises.
OP makes it sound like if you dont go to gym, you're obese or eat unhealthy. Most Somalis in their 20's are slim.
May Allah give you shifa abaayo

Going to gym isn't a prerequisite to attaining a fit and healthy lifestyle as many people do that without ever going to a gym. It's an individual undertaking so find out what best works for you best given your condition, as they say no one knows you better than yourself.
Having a bloody/metallic taste when doing exercises is quite normal than you think walaal. I used to experience it as well, firstly when i started to train after a period of being inactive and secondly when my activity/training sessions were longer.
So for me it was a common occurrence whenever i played sports took part in outdoor activities etc i would say that i experienced it the most when i was playing football and skiing. Had it checked out as well doctors told me it was ok and that most people will experience it whenever they take part in activities like sports etc.
