Oh wow I would of never thought stomping was great for the spine the jolts . I am no expert I am just thinking that way. I do have a rebounder in my shed use to use it back in the 70's I loved it was fun. So jumping is good for the bone rebuilding I would of never guessed that I will have to try this and hope for the best. Thank you for sharing your video loved it. I find it easier to listen to a video then reading. I am a visual person in many ways. Have a great day.
