COORDINATION TRAINING: The body is thrown out of balance by the instability of the air cushion and must restore it by small constant compensatory movements. This guarantees a huge training effect and makes the coordination training an equally demanding and effective full-body workout RELIEF SITTING: The ball cushion with knobs is suitable for dynamic sitting and to active back training, such as building core muscles, training spinal muscles and gently rocking intervertebral discs PROMOTE CIRCULATION: The buttoned surface also stimulates your circulation blood during training and makes your skin tingle. The non-slip underside of the cushion ensures maximum training safety MATCHING HAND PUMP: The balance cushion comes with a small hand pump. This allows you to fill the training cushion with air individually and vary the intensity of the training according to your needs and as you wish COMPACT DESIGN: diameter of approximately 33 cm. The perfect device for anyone who loves everyday life, e.g. B. want to train your back at work or on the go by driving or train NOTES 1. We recommend that you purchase a spherical seat cushion with a pump. With regular use, it may be a good idea to supply the spherical seat cushion several times with enough air, a pump makes this easier for you. 2. The pump opening is in the lower area of the cushion, but be sure to use the supplied pump. Hold the pump over the valve or plug it in and press air into the pillow several times, if the amount of air is optimal, simply remove the pump. 3. If you feel the pillow is too soft, fresh air can be added. If the pillow is too hard, you let air out; this variable use translates into much better personal use. 4. It is best to let the air out of the pillow when storing it, so that it can be reused if the pillow needs air.
