Any consistent exercise to bring rid of final grease??

Sounds stupid I know, but I am not a huge girl, I just requirement to loose about 20 lbs and tone up a bit. Anyways, the worst piece is that I have little backfat role on respectively side of my back and be wondering if anyone knew a a faultless exercise I can put into my workout that would be mostly to help achieve rid of that and tone that up ??
Thanks in Advance!
Rude and double-talk comments will be reported!! Cardio is your best bet. If you lose the pounds, the fat will come bad :-)
If you'd like to tone your subsidise though, you can do back extension.
Lay on you stomach, arms at you sides, and afterwards try to lift your cranium and shoulders up as high as you can using your vertebrae muscles. (google it for pics)
Good luck!
cardio for the starters is the best to reduce margarine. check your personal instructor but 1 month of cardio on a daily starting place for 60 mins is good for a start. also help the healthy lifestyle change like drinking good food.
