I'm underweight and i want to get abs but to get them i'd have to lose more weight?
My doctor’s told me if i lose anymore weight i would be putting my health at serious risk, but the only way to get abs is to get rid of the small layer of fat around my stomach and that would mean losing weight, what can i do?

i’m not sure how your stomach looks but i would just say do sit ups. I’ve still got a belly and you can still see part of my 6 pack (because i work out). just eat more foods with higher protein and do sit ups, i GUARANTEE you it WILL work.
also planning to lose the belly soon enough haha
