That type of exercise will usually turn your fat into muscle. In order to actually lose the fat you need to watch what you are eating also. What are your eating habits like?

Tiny breakfasts, Small Salads for lunch Small dinner!! I bearly every eat sweets or fatting stuff just trying to stay on fruit n veg!! So i actually eat really healty!

I feel the same, I need to lose my fat on my arms. Since time is so precious, I try to fit in doing exercise in the bathroom - you do a backward pushup from your bath tub - put your arms on the edge and push yourself up. I think cardio is one of the best ways to lose it along with toning up the muscles.

Most of my female training clients are not eating enough, especially protien. Protien is the building block for muscle. If you train and do not get enough calories you will actually begin to break down your own muscle as your body uses it for energy. Try increasing your daily calories to around 1800 (active female) and ingest 1 gm protien for each kilogram of body weight.
P.S. Fat will not turn into muscle!
Tiny breakfasts lead to weight gain do not starve yourself.
Let me know if I can help
