Do elliptical machines have the same benefits as a treadmill?

which one burns more calories and is most effective or are they both the same

What benefits will i get from kickboxing?

ive decided i wanted to start kickboxing to lose weight and learn how to defend myself. I have fat/wide butt and fat thighs and i was wondering if kickboxing can give you a smaller butt and smaller thighs. (im a teen guy) (do u know any more benifits i can get)
what im asking is will kickboxxing give me a smaller butt and thighs

What are the benefits of kickboxing and how long until I notice a difference in my body if I start?
