The assisted Crunch belongs to the standard exercises of the abdominal training. The straight abdominal muscles get stressed in an optimal way. The legs get alternately pulled towards the chest. This increases the meaning of the dynamic aspect. The straps of the VarioSling have an angle of 60-45 degree and point towards the legs. The suspension point is placed behind the head.
