Resistance Training

should I cut out resistance training and do cardio every day?

I am 18 yrs old 5’9″ and weigh 160lbs. I lost 90 pounds but i still have flab around my stomach. I do cardio every other morning and resistance training the days i dont do cardio. should I focus on the cardio and do it every day then come back to resistance training after i lose that flab?

Both of these separately will only do so much to lessen stomach fat. however, together, these two workouts will burn the fat easily.
The best thing to do, would be to do cardio coupled with resistnce training. I would also consider doing weighted workouts, using weight plates.
The stomach/core/and abs are like any other muscle, and in order to lose fat and tone, you must use weights and do toning workouts. First build muscle, then start to tone!
You can try a supplement called Animal Cuts. This helps burn fat, while building and toning muscle.
