What can I take to help me get visible abs and toned legs?

I think of an average weight and height. I'm 167 cm tall, 55 kg. That's like 5'5'' and 121 lb. I'm a female. I want to have visible abs and toned butt and legs. What products can I take to help me get that with regular exercise (3 times a week)? How long is it gonna take? I've stopped... show more I think of an average weight and height.

How long is it gonna take? I've stopped exercising like 6 months ago, I was so busy with school so how difficult is it to have a nice body? Will I be able to have a better body in a month? Thanks :D
Update: I'm not fat free btw
