What are some workouts that someone who hates cardio workouts and has asthma do to loose weight?

Hey guys, I wanna drop anywhere from 15-20lbs. Im 23 yrs old, 5'2", and 140lbs. I don't like many cardio workouts like running/jogging/walking because they're no fun! Also I can't do the tougher workouts like zumba because of my asthma. However I absolutely love strength workouts. I can do those all day long, they are fun, challenging and they don't bother my lungs. My question is: Can I just do strength workouts and still see results?
