Is kickboxing a fun sport and does it get you into shape?

Im a 15 year old girl but i've been interested in kickboxing for years! my dad always said no casue im a girl, but finally he said yes! I dontt think i want to compete right away, i want it to get in shape and i have just always had a strange interest in it, i don't know why!! So do you think this would be good for me??? Im really intrested in it and just want to know if it would be a good idea!!
