Would it be safe to put the Vibrogym on a judo mat?
The judo mats provided by us are entirely stable enough to put the Vibrogym on, as long as the machine is used according to the advice given by us. For example, if you are pulling on the handle with you whole body weight, the Vibrogym is likely to tilt. You should aim to be fully balanced unaided during exercises, only using the handle to steady yourself if necessary.
