If i want to start kickboxing which gym should i choose: LA Boxing or Liberty Boxing?

i live in south jersey. im 15. i want to start kickboxing as a way to stay in shape. which gym is cheaper and has the best results? i went on both websites and LA Boxing had more information about everything and it seems like the gym id choose but idk if its just all advertising, r the results real? like it says u burn 800 to 1000 calories in an hr. Liberty boxing doesnt have as much info on the website. anyone have experience at either gym? what r the workouts like?
