According to statistics from the University of Heidelberg, around 80 percent of all Germans suffer from back pain at regular intervals. This was a good enough reason for the manufacturer of training and therapy equipment in Prien am Chiemsee to introduce two new products onto the market in 2010 for relaxation, therapy and back muscle strengthening. The oval Pendel Balance Ball is one of these new products. Thanks to its shape, the Pendel Balance Ball has a larger seating area, more stability and encourages deeper relaxation. The new Dynair Extreme trains the entire body. It is a ball cushion that forces the athlete to balance out the swaying movements that he/she has caused. The German healthy back campaign, "Aktion Gesunder Rücken e.V.", has already judged both products as being particularly back-friendly, awarding them the AGR seal of approval.
