Do you think the mini trampolines would be an effective form of excerise for toning and cardio? Also, would they be effective in improving someones balance?

Well,my parents were thinking about buying a trampoline for our home.My mom had me look up places where you could buy trampolines,but i never thought of a place.So,where is a place that you can buy trampolines in simi valley??

Do you just walk on them or jog or what?

You put it in water and it is like a trampoline and you jump on it and off of it.
