Nearly 80 percent of the Dutch sometimes suffer from it:back pain. Fortunately, you can prevent back problems caused by sitting too much or incorrect posture.
How? By training.
The box Back training contains fifty cards with exercises. The cards contain drawings and explanations for a workout that stretches the spine and your posture improves. You can do warm-up exercises first, then train the muscles and end with a relaxation exercise †
