Thanks for the description! I was envisioning those machines that have a big belt that goes around your butt and jiggles your fat at a fast oscillation rate that was popular in the 50's!
Yes, this does sound like intense exercise. The work your body does to maintain balance is good whole body exercise, and this seems to really accelerate it. If your joints can handle it, your j-pouch should too. I know with my enteropathic arthritis, it would be a pain machine for me! So, I am not getting one. For me, the old fashioned walking, hiking, stretching, and house/yard work is plenty to keep me worn out!
One word of warning. You should take a day off if you are having a lot of muscle pain. It means you over did it. Then resume with shorter workouts. If you work out while in pain, you are more likely to injure yourself.
