Changes

The instructions that come with the Thumper say that you should not press the thumper against the body, but just use the weight of the Thumper, which is surprisingly heavy. I ignore this advice and push the thumper hard against problem areas. This puts extra strain on the motor, and my Thumper is suffering a little, but has been going in this way for years. If you do push the Thumper against the injury, you may destroy it, so follow my example at your own risk.
