I first heard of the bellicon trampoline during rehab. Though the therapists advised against it, I decided to try it. I had bad pains in the lower back region, in the sacroiliac joint, and massive muscle tension.
After only the first training unit (20 minutes) I felt considerable pain relief because my muscles relaxed and I got more mobility of the sacroiliac joints. They loosened due to the see-saw and swinging motion. For the positive effects I decided to buy the device.
I put the mini trampoline in the basement in front of the TV. I also use it with a music station, then it is even more fun.
