Most of the people I know that exercise frequently are worried about losing weight. I realize that is my major reason for tugging me off of the couch from time to time! So I did a little research on rebounding and discovered that this type of workout, on a fitness trampoline, consumes a lot more calories than jogging on a flat surface will. That is pretty good exercise if you ask me! I also discovered that rebounding is really a low impact workout. It turns out that the spring effect on the rebounder minimizes tension on your joints. It also keeps your joints and muscles more flexible which helps support your power, flexibility and balance. trampoline nets
