Many people want a six-pack. The desire for a dream figure has grown in recent years. Many athletes try to sculpt their bodies in a gym. Other athletes prefer to train alone at home. Every stomach can be effectively trained with an abdominal roller. A six-pack is not necessarily to be expected, but the stomach becomes much firmer after a few training sessions. Before the device can be used, it must first be assembled. To do this, the handles must be screwed onto both sides of the roller. Many models can only be used up to a body weight of 100 kg. Many devices are of very high quality. They can therefore be used for training over many years. Abdominal rollers, which are suitable for a higher body weight, are usually made even more robust.
