Incorporate more compound movements; for example, when you say single lifts, do you mean bicep curls? Because curls are pretty useless. I'd say replace curls with deadlifts, but if you don't have access to the gym, maybe replace it with more pushups. And the "lifts with both hands" I'm assuming are double arm dumbbell curls, which I would replace with clean and press, which will also hit more muscles in the body and cut fat more quickly. If that's your goal, anyway. You'll have to stretch your arms a little more before you start so you don't pull anything with the added strain to your arms. Side lifts I would probably replace with tricep dips, which you can do at home, and possibly some pullups, which again will help more than curls. If you can't do pullups at first, you can always jump up and let yourself down slowly to get started until you can pull yourself all the way up.

I could also send you an old marathon training guide that's designed to build your endurance and make other forms of aerobic exercise easier while greatly increasing the distance you can run.

What's your rest period between different exercises? What are your warm-ups, and what stretches do you do before them?

Oh, and maybe add another set of squats; maybe do one short set at the beginning and another at the end of the workout. Squats are OP.

Oh, here's the marathon guide. I forgot I had already uploaded it to imgur. This isn't for cutting fat primarily, it's for increasing endurance. To cut fat, you should always walk/run for a minimum of 30 minutes to see any real results (unless the rest of your workout is first, in which case you should make sure you aren't in the heat, because you'll dehydrate much more quickly.)

Most cardio will also interfere a bit with gaining muscle, so the combination of intense aerobic training and compound movement strength exercises will succeed in reducing fat more effectively without worrying about gaining back too much weight in the form of muscle.
