I am not sure which two to take either aerobics, pilates, or cardio kickboxing???

I want to get my body tone and lose some weight. I mean not like 30 pounds or anything because then I would be too skinny. i weigh about 126-130 right now about 5'4 maybe 10 pounds just to feel comfortable in a bathing suit. I want my arms to be kind of cut not manly or anything but you know fit. I want to get back in shape and fit. Which two do you prefer. I mean I think I definately want to take cardio kickboxing cuz that seems like i can take some agression out or anger you know. some stress. what do you think.???
