One of my favorite forms of exercise in the past several years is "rebounding" ? performing a variety of movements on a mini-trampoline. Usually no larger than a yard in diameter, most often circular, but sometimes square, a rebounder is safe and easy to use, relatively inexpensive, time efficient, and enjoyable.
Another major plus is the convenience factor. A rebounder can be used just about anywhere where there is a flat, supporting surface. So, unless you live in some place with extremely low ceilings or where the floor is about to collapse, you can rebound in the comfort of your own home. It is wonderful for those days when the roads are slicked with ice or you just don?t have the time or energy to run down to the gym.
