Maybe it would be better to switch up the split of your cardio and weight training, so that you can focus all the way on one.
Maybe do your cardio in the morning, and lift in th afternoon for example.
Or simply warm up for 10 minutes with cardio to get the blood flowing and ready to pump to your muscles, lift for 45 minutes-1 hr or however long you're jonesin' for, then do more cardio after. I would keep your lifts to mostly compound movements for just general strength.
Or try a workout like this
I think either of these options would be better than running back and forth from lifting to the elliptical. Plus, one needs to change their workout every 4-6 weeks (unless you powerlift, and even then you need to mix it up). I think this is the root of your lack of results.
