I really enjoy rebounding. It helped me jump into my weight loss program. It's fun and easy. I wanted to try some routines so I bought two videos to give it a try. I found the trainers slightly annoying and the routines to be dull. I liked learning the basic types of bounces but it seemed VERY repetitive after the first 10 minutes. I prefer to use the basic moves I learned from the DVD's and do my own thing. I keep track of my heart rate on a monitor and can change my intensity that way.Buy one and see if you like it, I wouldn't buy them all unless you try one and REALLY love it.
