Need alot of advice please! Flabby arms

codygoodman15

I am no where near the weight I wanna be I still have 40 pounds to go but I was 270 and now I'm down to 203 I am noticing everywhere I look on my body has flabby skin especially my arms and inner thighs. I have only been using the treadmill so not much work on my arms. I was wondering would someone have to have surgery to get rid of flabby skin or can it be toned and look good. I want to tone as I'm losing weight. What exercises would be good for getting rid of saggy skin if there is any help for it.
