Do my fellow rebounders see the same results from this form of cardio as you do from more "traditional" forms like running, step aerobics, etc? For some reason, it's near impossible for me to break a sweat on the darn thing--even wearing ankle weights. When I run, I sweat so I don't understand....? I've heard so many wonderful things about rebounding like lymphatic movement, cellular strengthening, less joint impact, etc, but does it really burn fat like other types of cardio? What are your experiences?
