You will not regret the purchase of your rebounder mouseclick,
One of the many benefits of rebounding provides the necessary stimulus for pumping the lymph system, which very few other exercises do.
The blood has the heart muscle, whereas the lymph has no such mechanical pump at all, but rebounding will create the circulation of the lymph and thereby prevent lymph-related diseases....including cancer.
Go easy while fasting, but these are the benefits of rebounding........
